% \maketitle
%
% \begin{abstract}
% The |todonotes| package allows you to insert to--do items in your
% document. At any point in the document a list of all the inserted
% to--do items can be listed with the |\listoftodos| command.

%
% \newpage
% \section{Introduction}
%
% The |todonotes| package makes three commands available to the
% user: |\todo[]{}|, |\missingfigure{}| and |\listoftodos|.
% |\todo[]{}| and |\missingfigure{}| makes it possible to insert
% notes in your document about things that has to be done later
% (todonotes \ldots).
% I developed the basic functionality of the package while I worked
% on my bachelor project.
% 
% Some alternatives for the todonotes package are:
% \begin{itemize}
% \item \href{http://ctan.org/pkg/easy-todo}{easy-todo}\\
% Depends on |color|, |tocloft| and |ifthen|, small feature set.
% \item \href{http://ctan.org/pkg/fixmetodonotes}{fixmetodonotes}\\
% Depends on |graphicx|, |color|, |transparent|, |watermark|,|fix-cm|, |ulem| and |tocloft|, small feature set.
% \item \href{http://ctan.org/pkg/todo}{todo}\\
% Depends on |amssymb|, medium feature set.
% \item \href{http://ctan.org/pkg/fixme}{fixme}\\
% Large package with a lot of features.
% \end{itemize}
% The main reason for considering other packages is that the todonotes 
% package is quire large and relies heavily on tikz.
% This can slow down compilation of large documents significantly.
% The mentioned alternatives have a different feature set and does not 
% rely on tikz, which makes them require less ressoureces.
%
%
% \subsection{Usage}
%
% \DescribeMacro{\todo}
% My \index{\todo}most common usage of the todonotes package, is to 
% insert an todonotes somewhere in a latex document. 
% An example of this usage is the command 
%
% |\todo{Make a cake \ldots}|, 
% 
% \noindent
% which renders like\todo{Make a cake \ldots}.
% The |\todo| command has this structure: 
% |\todo|\oarg{options}\marg{todo text}.
% The |todo text| is the text that will be shown in the todonote and
% in the list of todos. The optional argument |options|, allows the
% user to customize the appearance of the inserted todonotes.
% For a description of all the options see section
% \ref{subsecTodoOptions}.
%
%
% \DescribeMacro{\missingfigure}
% The |\missingfigure| command inserts an image containing an 
% attention sign and the given text.
% The command takes only one argument
% |\missingfigure|\marg{text}, a text string that could
% describe what the figure should consist of.
% An example of its usage could be 
%
% |\missingfigure{Make a sketch of the structure of a trebuchet.}| 
%
% \noindent
% which renders like.
%
% \missingfigure{Make a sketch of the structure of a trebuchet.}
%
%
% \DescribeMacro{\listoftodos}
% The |\listoftodos| command inserts a list of all the todos in the
% current document. |\listoftodos| takes no arguments.
% For this document the list of to--do's looks like.
% \listoftodos
% \vspace{0.5cm}
%
% \DescribeMacro{\todototoc}
% The |\todototoc| command adds an entry to the table of contents for 
% list of todos. The command should be placed right before the 
% |\listoftodos| command.
%
% \subsection{Package options}
% \label{subsecPackageOptions}
% \DescribeMacro{disable}
% If the option |disable| is passed to the package, the macros
% usually defined by the package (|\todo|, |\listoftodos| and
% |\missingfigure|) are defined as macros with no effect, and thus
% all inserted notes are removed.
%
% \DescribeMacro{obeyDraft, obeyFinal}
% When the option |obeyDraft| is given, the package checks
% if the one of the options |draft|, |draftcls| or |draftclsnofoot| 
% is given (this option is usually given to
% the documentclass). If the |draft| option is given, the
% functionality of the package is enabled and otherwise the effect
% of the package is disabled.
% The option |obeyFinal| does something similar, except that the 
% todonotes package is only disabled if the |final| option given.
%
% \DescribeMacro{danish, german, ngerman, english, french, swedish}
% \DescribeMacro{spanish, catalan, italian}
% \DescribeMacro{portuguese, dutch, croatian}
% Use translations of the text strings 
% ''List of todos'' and ''Missing figure''.
% The default is to use none of these options, which results in
% english text strings.
% Currently the following languages are supported: 
% catalan,
% croatian,
% danish,
% dutch,
% english, 
% french,
% german,
% ngerman,
% italian,
% portuguese,
% spanish and
% swedish.
% 
% \DescribeMacro{colorinlistoftodos}
% Adds a small colored square in front of all items in the Todo
% list. The color of the square is the same as the fill color of the
% inserted todonote.
% This can be useful if there are different types of todos 
% (insert reference, explain in detail, \ldots) where the color of
% the inserted todonote marks the type of todo.
%
% \DescribeMacro{color}
% \DescribeMacro{backgroundcolor}
% \DescribeMacro{linecolor}
% \DescribeMacro{bordercolor}
% These options sets the default colors for the todo command.
% There is three colors that can be specified. The border color
% (default |bordercolor=black|) around the inserted text, the color
% behind the inserted text (default |backgroundcolor=orange|) and
% the color of the line connecting the inserted textbox with the
% current location in the text (default |linecolor=orange|). 
% Setting the |color| option to |val| passes this value on to the 
% background and line color options.
% The specified colors must be valid according to the 
% |xcolor| package.
% 
% \DescribeMacro{textwidth}
% |textwidth=length| sets the width of a todo item in the margin to
% |length|. The width of inline todonotes will allways be the same 
% as the current line width.
%
% \DescribeMacro{textsize}
% |textsize=value| sets the default text size of the inserted
% todonotes to the given value.
% Value is the ''name'' of the used font size, eg. if the desired
% fontsize is |\tiny| use |textsize=tiny|. The default value is 
% |textsize=normalsize|.
%
% \DescribeMacro{prependcaption}
% The |prependcaption| option triggers a special behaviour of the
% |caption=val| option for the todo command, where the given value
% |val| is inserted in the inserted todonote.
% 
% \DescribeMacro{shadow}
% If the |shadow| option is given, the inserted todonotes will be
% displayed with a gray shadow.
% I expect that the option will trigger problems with tikz versions
% prior to 2.0.
%
% \DescribeMacro{dvistyle}
% When a document with todonotes is compiled with plain latex (to a
% dvi-file), there is an issue with the visual
% appearance\footnote{The problem is placement of text inside the
% colored boxes.}.
% The option |dvistyle| changes the appearance of the inserted
% todonotes to avoid this problem.
%
% \DescribeMacro{figwidth}
% The |figwidth=length| option sets the default width of the figure
% inserted by the |\missingfigure| command. 
% The default value is |\linewidth|.
%
% 
%
% \subsection{Options for the todo command}
% \label{subsecTodoOptions}
% There are several options that can be given to the |\todo|
% command. All the options are described here and often I have
% included examples of the change in visual appearance.
% Default values for these options can be set using the presetkeys 
% command.
% \begin{verbatim}
% \presetkeys{todonotes}{fancyline, color=blue!30}{}
% \end{verbatim}
%
% \DescribeMacro{disable}
% The |disable| option can be given directly to the todo command.
% If given the command has no effect.
%
% \DescribeMacro{color}
% \DescribeMacro{backgroundcolor}
% \DescribeMacro{linecolor}
% \DescribeMacro{bordercolor}
% These options set the color that is used in the current todo
% command.
% The color classes is the same as used in the color package
% options, see section \ref{subsecPackageOptions}.
% Default values can be set by the color
% options when the todonotes package is loaded.
% \todo[color=green!40]{And a green note}
% The todo notes inserted in this paragraph is created with the
% command
% |\todo[color=green!40]{And a green note}|.
% The color of the inserted note could be used to mark different
% types of tasks (insert references, explain something in detail,
% \ldots), this could be streamlined by defining new commands like
% below.
% \begin{verbatim}
% \newcommand{\insertref}[1]{\todo[color=green!40]{#1}}
% \newcommand{\explainindetail}[1]{\todo[color=red!40]{#1}}
% \end{verbatim}
% An example that uses all of the color options is given
% below\todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
% bordercolor=red]{Anything but default colors}.
% \begin{verbatim}
% \todo[linecolor=green!70!white, backgroundcolor=blue!20!white,
% bordercolor=red]{Anything but default colors}.
% \end{verbatim}
%
%
% \DescribeMacro{line / noline}
% If you want to get rid of the line connecting the inserted note
% with the place in the text where the note occurs in the latex
% code, the option |noline| can be used.
% \todo[noline]{A note with no line connecting it to the placement
% in the original text.}
% |\todo[noline]{A note with no line ...}|
% \vspace{1.0cm}
% 
%
% \DescribeMacro{inline / noinline}
% It is possible to place a todonote inside the text instead of
% placing it in the margin, this could be desirable if the text in
% the note has a considerable length.
% |\todo[inline]{A todonote placed in the text}|
% \todo[inline]{A todonote placed in the text}

% \begin{wrapfigure}[1]{r}[20mm]{40mm}
% \begin{tikzpicture}
% \draw[red] (0, 0) circle(0.45);
% \draw[green] (1, 0) circle(0.45);
% \draw[blue] (2, 0) circle(0.45);
% \end{tikzpicture}
% \caption{A text explaining the image.
% \todo[inline]{Fill those circles \ldots}}
% \end{wrapfigure}
% Another usage for the inline option is when you want to add a
% todonote to a figure caption.
%
% \begin{verbatim}
% \begin{wrapfigure}{r}[20mm]{40mm}
% \begin{tikzpicture}
% \draw[red] (0, 0) circle(0.45);
% \draw[green] (1, 0) circle(0.45);
% \draw[blue] (2, 0) circle(0.45);
% \end{tikzpicture}
% \caption{A text explaining the image.
% \todo[inline]{Fill those circles \ldots}}
% \end{wrapfigure}
% \end{verbatim}
%
% \DescribeMacro{size}
% |size=val| changes the size of the text inside the todonote.
% The commands used to create the notes below are \\ \noindent
% |\todo[size=\Large]{A note with a large font size.}|
% and \\ \noindent
% |\todo[inline, size=\tiny]{Note with very small font size.}|.
% \todo[size=\Large]{A note with a large font size.}
% \todo[inline, size=\footnotesize]{Note with very small font size.}
%
% \DescribeMacro{list / nolist}
% When the option |nolist| is given, the todo item will not appear in
% the list of todos.
%
% \DescribeMacro{caption}
% The |caption| option enables the user to specify a short
% description of the todonote that are inserted in the list of
% todos instead of the full todonote text.
% \todo[caption={Short note}]{A very long and tedious note that
% cannot be on one line in the list of todos.}
% \begin{verbatim}
% \todo[caption={Short note}]{A very long and tedious note that
% cannot be on one line in the list of todos.}.
% \end{verbatim}
% The effect of this option is altered with the package option
% |prependcaption| or the |prepend| / |noprepend| option for the
% todo command.
%
% \DescribeMacro{prepend / noprepend}
% The options |prepend| and |noprepend| can be used for setting
% whether a given caption should be prepended to the todonote or
% not.
% Globally this can be set using the |prependcaption| option for the
% package.~\todo[prepend, caption={Short note with prepend}]{A very
% long and tedious note that cannot be on one line in the list of
% todos.} Below is the effect of the option shown using the code:
% \todo[noprepend, caption={Short note with noprepend}]{A very long
% and tedious note that cannot be on one line in the list of
% todos.}
% \begin{verbatim}
% \todo[prepend, caption={Short note with prepend}]{A very long and tedious 
% note that cannot be on one line in the list of todos.}.
% \todo[noprepend, caption={Short note with noprepend}]{A very long and 
% tedious note that cannot be on one line in the list of todos.}.
% \end{verbatim}
%
% \DescribeMacro{fancyline}
% The |fancyline| option inserts a curved arrow, pointing from the inserted 
% note to the insertion point.
% \todo[fancyline]{Testing.}
% The option is used like this:
% \begin{verbatim}
% \todo[fancyline]{Testing.}
% \end{verbatim}
%
%
% \DescribeMacro{author}
% The |author| option takes a parameter, the name of the author.
% The given name is inserted in the todonote.
% \todo[author=Xavier]{Testing author option.}
% \todo[author=Xavier, inline]{Testing author option.}
% \begin{verbatim}
% \todo[author=Xavier]{Testing author option.}
% \todo[author=Xavier, inline]{Testing author option.}
% \end{verbatim}
%
%
% \DescribeMacro{inlinewidth}
% The |inlinewidth| option makes it possible to alter the width
% of inline todos.
% \todo[inline, inlinewidth=5cm]{Testing the option inlinewidth.}
% \begin{verbatim}
% \todo[inline, inlinewidth=5cm]{Testing the option inlinewidth.}
% \end{verbatim}
%
%
% \DescribeMacro{inlinepar / noinlinepar}
% The options |inlinepar| and |noinlinepar| (default) determine whether the inserted inline 
% todonote is sorrounded with \texttt{par} macros that enforce new lines
% prior to and after inserted inline todonotes.
% \todo[inline, inlinewidth=5cm, noinlinepar]{Testing the option inlinepar.}
% This is a line after the inserted todonote.
% \begin{verbatim}
% \todo[inline, inlinewidth=5cm, noinlinepar]{Testing the option inlinepar.}
% \end{verbatim}
%
%
% \subsection{Options for the missingfigure command}
%
% \DescribeMacro{figwidth}
% The |figwidth=length| option sets the width of the figure inserted by the
% |\missingfigure| command.
% Length values below $6cm$ might trigger some problems with the
% visual appearance.
% Try to compare the default of the missing figure command, when the
% option is given or not. 
% \begin{verbatim}
% \missingfigure[figwidth=6cm]{Testing a long text string}
% \end{verbatim}
% \missingfigure[figwidth=6cm]{Testing a long text string}
% \begin{verbatim}
% \missingfigure{Testing a long text string}
% \end{verbatim}
% \missingfigure{Testing a long text string}
% \begin{wrapfigure}[1]{r}[2cm]{6cm}
% \missingfigure[figwidth=6cm]{Add a test image \ldots}
% \end{wrapfigure}
% Another usage of the option is when |\missingfigure| is used in
% the wrapfigure environment.
% \begin{verbatim}
% \begin{wrapfigure}[1]{r}[2cm]{6cm}
% \missingfigure[figwidth=6cm]{Add a test image \ldots}
% \end{wrapfigure}
% \end{verbatim}
% 
% \DescribeMacro{figheight}
% The |figheight=length| option changes the height of the inserted 
% missing figure.
% The default height is 4cm and using values lower than this might 
% cause the warning sign to pop out of the gray area.
% \begin{verbatim}
% \missingfigure[figheight=6cm]{Testing a long text string}
% \end{verbatim}
% \missingfigure[figheight=6cm]{Testing}
%
%
% \DescribeMacro{figcolor}
% The |figcolor=color| options sets the background color of 
% inserted missing figures.
% The default color is |black!40|.
% \begin{verbatim}
% \missingfigure[figcolor=white]{Testing figcolor}
% \end{verbatim}
% \missingfigure[figcolor=white]{Testing figcolor}
%
%
% \subsection{Options for the listoftodos command}
% The |\listoftodos| command takes one optional argument, that
% defines the name of the inserted list of todos.
% \begin{verbatim}
% \listoftodos[I can be called anything]
% \end{verbatim}
% 
%
%
% \subsection{Known issues}
% \subsubsection{Package loading order}
% The todonotes package requires the following packages.
% \begin{multicols}{2}
% \begin{itemize}
% \item ifthen
% \item xkeyval
% \item xcolor
% \item tikz
% \item calc
% \item graphicx (is loaded via the tikz package)
% \end{itemize}
% \end{multicols}
% \noindent
% When todonotes are loaded in the preamble, the package checks
% if these packages all are loaded. If that is not the case it loads
% the missing packages with no options given.
% If you want to give some specific options to some of these
% packages, you have to load them \emph{before} the todonotes
% package, otherwise you will get an ''Option clash'' error when
% latex works on the document.
% 
% If both the menukeys and the xcolor (with the option \verb!table!) 
% package should be loaded, the following order must be used.
% \begin{verbatim}
%\usepackage[table]{xcolor}
%\usepackage{todonotes}
%\usepackage{menukeys}
% \end{verbatim}
%
% \subsubsection{Spacing around inserted notes}
% Inserted todo commands will eat the white space after the command.
% \begin{verbatim}
%Testing\todo{Does this eat the space?} testing.\end{verbatim}
% \noindent
% Testing\todo{Does this eat the space?} testing.
%
% This can be prevented by adding curly parenthesis after the 
% todo command, like shown below.
% \begin{verbatim}
%Testing\todo{Does this eat the space?}{} testing.\end{verbatim}
% \noindent
% Testing\todo{Does this eat the space?}{} testing.
%
% \subsubsection{Wrapping of long lines in list of todos}
% When a document is compiled with latex (and not pdflatex) long
% items in the list of todos are not wrapped into several lines, and
% do instead continue to the right out of the page.
%
%
% \subsubsection{Conflicts with the amsart documentclass}
% The |amsart| document class redefines some internal commands that
% is used by the todonotes package, this will cause an malfunctioning
% |\listoftodos| command.
% The following code to circumvent the problem was given by Dan
% Luecking on comp.text.tex
% \begin{verbatim}
% \makeatletter
%   \providecommand\@dotsep{5}
% \makeatother
% \listoftodos\relax 
% \end{verbatim}
%
% NOT TESTED
% NOT TESTED
% NOT TESTED
%
% Dominique suggests the following workaround.
% \begin{verbatim}
% \makeatletter
% \providecommand\@dotsep{5}
% \def\listtodoname{List of Todos}
% \def\listoftodos{\@starttoc{tdo}\listtodoname}
% \makeatother
% \end{verbatim}
%
%
%
% \subsubsection{Unknown option ''remember picture''}
% If latex throws the error
% \begin{verbatim}
% Package tikz Error: I do not know what to do with the option ``remember picture''.
% \end{verbatim}
% It probably means that your latex installation is outdated, as
% only newer versions of latex driver for tikz supports the
% |remember picture| option.
% For additional info consult 
% ''Section 9.2.2 Producing PDF Output'' in the tikz manual. 
% \url{http://www.ctan.org/tex-archive/graphics/pgf/base/doc/generic/pgf/pgfmanual.pdf}
%
%
% \subsubsection{Todonotes wrongly placed in the margin}
% When using some document classes or packages, the todonotes inserted in the 
% page margin can be placed quite oddly.
% This is often caused by a wrong value of the |\marginparwidth| lenght.
% Try using the code below in your preamble to see if this cures the problem.
% \begin{verbatim}
% \setlength{\marginparwidth}{2cm}
% \end{verbatim}
%
% If the todonotes are inserted in the wrong margin, the solution is the 
% |\reversemarginpar| command.
% When this command is issued the following marginpars (which todonotes 
% relies on) is inserted in the other margin.
%
% \subsubsection{Reduce number of warnings}
% If the width of the inserted todonotes is forced to be larger than the 
% available space in the margin, a lot of warnings are issued.
% This can be reduced with the following code.
% \begin{verbatim}
% \usepackage[textwidth=3.7cm]{todonotes}
% \setlength{\marginparwidth}{3.7cm}
% \end{verbatim}
%
%
% \subsubsection{Todonotes in footnotes}
% Placing todonotes in footnotes throws a lot of errors.
% Richard Stanton comes with the following work around.
% \begin{verbatim}
% \renewcommand{\marginpar}{\marginnote}
% \end{verbatim}
%
%
% \subsubsection{List of todo heading is not correctly formatted}
% If using natbib, the todonotes list title gets screwed up unless 
% you do something like this:
% \begin{verbatim}
% \makeatletter\let\chapter\@undefined\makeatother 
% \end{verbatim}
% Suggestion by Richard Stanton.
%
% 
% \subsubsection{Trouble with classicthesis.sty}
% \href{http://tex.stackexchange.com/questions/33423/todonotes-produces-double-inline-notes-instead-of-single-margin-note-with-class}{Problem description on tex.stackexchange.com}.
% 
% Solution by Stefan Kottwitz. 
% The problem is caused by the redefinition of |\marginpar| in 
% classicthesis.sty. |\marginpar| is used by todonotes. 
% It can be fixed by restoring the original meaning, if you don't 
% need the classicthesis marginpar style. 
% Just add this to your document preamble:
% |\let\marginpar\oldmarginpar|
%
%
% \subsection{Things to improve}
% This is a list of things I consider to improve sometime in the
% future. It have not been done yet as I lack the time or skills to
% implement them.
% Patches with implementations of these tasks will be appreciated
% and might be included in the package if it will improve the
% package quality.
%
%
% \subsubsection{Owner information}
% Option for the todo command.
% \begin{verbatim}
% \todo[owner={Fabrice}]{Stuff}
% \end{verbatim}
% Add info on who ''owns'' the current todo. 
% Idea: Fabrice Niessen
%
%
% \subsubsection{Due date}
% Option for the todo command.
% \begin{verbatim}
% \todo[due=2008-12-07]{Stuff}
% \end{verbatim}
% Add info on when the current todo is due.
% Might be enhanced by a time line of the todos that have a due date
% assigned.
% Idea: Fabrice Niessen
%
%
% \subsubsection{Mark accomplished todos}
% \begin{verbatim}
% \todo[done]{Stuff}
% \end{verbatim}
% Idea: Fabrice Niessen
%
%
%
% 
% 
% \subsection{Usage methods}
% In this section I have collected some different methods to use the
% |todonotes| package.
%
%
% \subsubsection{Define new commands with fixed options}
% Often there is a need for marking different classes of things to
% do (add reference, rewrite, \ldots).
% One way to do this, is to define some new commands as shown below
% (idea from Florent B.).
% \begin{verbatim}
% \newcommand{\addref}{\todo[color=red!40]{Add reference.}}
% \newcommand{\rewrite}[1]{\todo[color=green!40]{#1}}
% \end{verbatim}
% To distinguish between the different types of todos, the
% |todonotes| package can be loaded with the |colorinlistoftodos|
% option, which adds small colored squares to the list of todos.
% \begin{verbatim}
% \usepackage[colorinlistoftodos]{todonotes}
% \end{verbatim}
% 
%
% \subsubsection{Define new commands with arbitrary default options}
% If you do not like the default values of the standard todo command, 
% it is possible to define a new command with the similar 
% functionality of |\todo| with custom default values.
% \begin{verbatim}
% \newcommand{\todoredefined}[2][]
% {\todo[color=red, #1]{#2}}
% \end{verbatim}
% \newcommand{\todoredefined}[2][]
% {\todo[color=red, #1]{#2}}
% \todoredefined{Test of newly defined command.}
% The new command can now be used like shown below
% \begin{verbatim}
% \todoredefined{Test of newly defined command.}
% \todoredefined[color=green]{Test of newly defined command, requesting a green color.}
% \end{verbatim}
% \todoredefined[color=green]{Test of newly defined command, requesting a green color.}
% This can be done with all the accepted options for the |\todo| command.
% 
%
%
% \subsubsection{Enumerate todonotes}
%
% If the inserted todonotes should be enumerated, it is possible to define 
% a new command with the desired behaviour.
% \begin{verbatim}
% \newcounter{todocounter}
% \newcommand{\todonum}[2][]
% {\stepcounter{todocounter}\todo[#1]{\thetodocounter: #2}}
% \end{verbatim}
% \newcounter{todocounter}
% \newcommand{\todonum}[2][]
% {\stepcounter{todocounter}\todo[#1]{\thetodocounter: #2}}
% The idea is to define a new counter |todocounter|, and insert the 
% \todonum{A numbered todonote.}
% value of the counter in each todonote.
% The new command can be used like
% \todonum{Another numbered todonote.}
% \begin{verbatim}
% \todonum{A numbered todonote.}
% \todonum{Another numbered todonote.}
% \end{verbatim}
%
%
% 
% \subsubsection{Comments ''a la Word''}
%
% Fabrice Niessen sent me the following use case.
% The idea is to define a new command |\mycomment| which adds a
% counter and optionally the initials of the author to the inserted
% todonote.
% 
% \begin{verbatim}
% \newcounter{mycomment}
% \newcommand{\mycomment}[2][]{%
%    % initials of the author (optional) + note in the margin
%    \refstepcounter{mycomment}%
%    {%
%        \setstretch{0.7}% spacing
%        \todo[color={red!100!green!33},size=\small]{%
%            \textbf{Comment [\uppercase{#1}\themycomment]:}~#2}%
%    }}
% \end{verbatim}
% \newcounter{mycomment}
% \newcommand{\mycomment}[2][]{%
%    \refstepcounter{mycomment}%
%    {%
%        \setstretch{0.7}%
%        \todo[color={red!100!green!33},size=\small]{%
%            \textbf{Comment [\uppercase{#1}\themycomment]:}~#2}%
%    }}
% 
% The command |\mycomment[HSM]{Testing first time.}| is displayed
% \mycomment[HSM]{Testing first time.}%
% like shown in the left margin, and another call of the command is
% added below |\mycomment[HSM]{Testing second time.}|.
% \mycomment[HSM]{Testing second time.}%
%
%
%
% \subsubsection{Combination with the fixme package}
%
% Thomas Arildsen has mailed me this use case. Check the
% documentation for the |fixme| package, as the code below relies
% directly on it (the |\FDUser| command is augmented when
% |\begin{document}| is reached).
% \begin{verbatim}
% \usepackage[user,nomargin]{fixme}
% \usepackage{todonotes}
% \newcommand{\FXUser}[2]{\todo[inline,size=\small]{{\bfseries #1:} #2}}
% \end{verbatim}
%
%
%
% \subsubsection{Altering the line spacing of todonotes}
%
% The |setspace| package lets you alter the line spacing of smaller
% sections of your document. The primary construct is the
% |spacing| environment, which is demonstrated below.
% \begin{verbatim}
% \begin{spacing}{0.5}
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.
% \end{spacing}
% \end{verbatim}
% \begin{spacing}{0.5}
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.
% \end{spacing}
%
% \vspace{0.25cm}
% Using the |spacing| environment we can define a new todonote
% command using the code below:
% \begin{verbatim}
% \newcommand{\smalltodo}[2][]
%     {\todo[caption={#2}, #1]
%     {\begin{spacing}{0.5}#2\end{spacing}}}
% \end{verbatim}
% \newcommand{\smalltodo}[2][]
%     {\todo[caption={#2}, #1]
%     {\begin{spacing}{0.5}#2\end{spacing}}}
% Todonotes with decreased line spacing can now be inserted as
% follows
% \smalltodo[size=\footnotesize]{
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.}
% \begin{verbatim}
% \smalltodo[size=\footnotesize]{
% Some lines with a decreased line spacing. This is accomplished
% using the setspace package that is included in standard latex
% distributions.}
% \end{verbatim}
%
% \noindent
% A different approach is given by Vitaly.
% \newcommand{\tinytodo}[2][]
%   {\todo[caption={#2}, size=\small, #1]{\renewcommand{\baselinestretch}{0.5}\selectfont#2\par}}
% \begin{verbatim}
% \newcommand{\tinytodo}[2][]
%   {\todo[caption={#2}, size=\small, #1]{\renewcommand{\baselinestretch}{0.5}\selectfont#2\par}}
% \end{verbatim}
% It looks like seen here.
% \tinytodo{
% Some lines with a decreased line spacing. This is accomplished
% without using any special packages.}
% \begin{verbatim}
% \tinytodo{
% Some lines with a decreased line spacing. This is accomplished
% without using any special packages.}
% \end{verbatim}
%
%
%
%
% \subsubsection{Marking new / old sections}
% Sometimes a whole section has to be marked by some means. You
% might want to try the following.
% \begin{verbatim}
% \todo[inline, caption={Some text}]{
% \begin{minipage}{\linewidth}
% Some text that might differ from the text given to the caption
% option.
% \end{minipage}
% }
% \end{verbatim}
% It is important to add the |caption={text}| option, otherwise
% latex will try to embed a minipage in the table of contents which
% triggers an error.
% Inside the minipage environment almost anything could be placed,
% except for other todo commands.
%
% To streamline use the following command was suggested by Stefan Pinnow.
% \newcommand\todoin[2][]{\todo[inline, caption={2do}, #1]{
% \begin{minipage}{\textwidth-4pt}#2\end{minipage}}}
% \begin{verbatim}
% \newcommand\todoin[2][]{\todo[inline, caption={2do}, #1]{
% \begin{minipage}{\textwidth-4pt}#2\end{minipage}}}
% \end{verbatim}
% This example renders like
% \begin{verbatim}
% \todoin{
% Some text.
% \begin{align}
% \sin(\theta)^2 + \cos(\theta)^2 = 1
% \end{align}
% A formula and a list
% \begin{itemize}
% \item	An item
% \end{itemize}
% }
% \end{verbatim}
% 
% \todoin{
% Some text.
% \begin{align}
% \sin(\theta)^2 + \cos(\theta)^2 = 1
% \end{align}
% A formula and a list
% \begin{itemize}
% \item	An item
% \end{itemize}
% }
%
%
%
% \subsubsection{Link to list of todos}
%
% Using the |hyperref| package it is possible to add a link from
% the inserted todonotes to the list of todos.
% The example were supplied by Andreas Plank.
% \begin{verbatim}
% % Define a counter for the inserted todonotes.
% \newcounter{todoListItems}
% \newcommand{\todoTrans}[2][ ]{
%   % Increment counter
%   \addtocounter{todoListItems}{1}
%   \todo[%
%     caption={\protect\hypertarget{todo\thetodoListItems}{}Translation},
%     #1]
%   {
%     #2 \hfill
%     \hyperlink{todo\thetodoListItems}{$\uparrow$}
%   }
% }
% \end{verbatim}
%
% \newcounter{todoListItems}
% \newcommand{\todoTrans}[2][ ]{
%   \addtocounter{todoListItems}{1}
%   \todo[
%     caption={\protect\hypertarget{todo\thetodoListItems}{}Translation},
%     #1]{
%    #2 \hfill
%    \hyperlink{todo\thetodoListItems}{$\uparrow$}
%  }
% }
%
% The idea behind the code is to embed a |hypertarget| in each entry
% in the list of todos. In the todonotes a link to the entry in the
% list of todos is inserted as an arrow that points upwards.
% Using the |\todoTrans| command like below, the following two notes
% have been inserted.
% \begin{verbatim}
% \todoTrans{papirsflyver}
% \todoTrans[inline]{damplokomotiv}
% \end{verbatim}
% \todoTrans{papirsflyver}
% \todoTrans[inline]{damplokomotiv}
%
%
% \pagebreak[4]
% \subsubsection{Numbered todonotes}
% 
% The inserted todonotes can be argumented with the current subsubsection number.
% The code is shown below.
% \newcommand{\ntodo}[2][]{\todo[#1]{\thesubsubsection{}. #2}}
% \begin{verbatim}
% \newcommand{\ntodo}[2][]{\todo[#1]{\thesubsubsection{}. #2}}
% \end{verbatim}
% By changing |\thesubsubsection| to |\thesection|, the current section number 
% can be inserted instead of the subsubsection number.
% The result looks \ntodo{A numbered todo.} like. 
% Which were generated by the code
% \begin{verbatim}
% \ntodo{A subsection numbered todo.}. 
% \end{verbatim}
%
%
% \subsubsection{Combining several modifications}
%
% \newcommand{\sstodo}[2][]
% {\addtocounter{todoListItems}{1}
% \todo[caption={\protect\hypertarget{todo\thetodoListItems}{}\thesection. #2}, #1]
% {\begin{spacing}{1} \hfill \hyperlink{todo\thetodoListItems}{#2} \end{spacing} }}
%
% Manduca have combined several of the modifications above into a highly specialized 
% todo command. 
% \sstodo{Small notes with links back to the list of todos.}
% She uses the code:
% \sstodo{Smart notes with links back to the list of todos.}
%
% \begin{verbatim}
% \newcounter{todoListItems}
% \newcommand{\sstodo}[2][]
% {\addtocounter{todoListItems}{1}
% \todo[caption={\protect\hypertarget{todo\thetodoListItems}{}\thesection. #2}, #1]
% {\begin{spacing}{1} \hfill \hyperlink{todo\thetodoListItems}{#2} \end{spacing} }}
% \end{verbatim}
% 
% Using this approach it is possible to customize the behavior of the inserted notes
% to a very high degree.
%
% 
% \subsubsection{Alter the appearance of the list of todos}
% Marco Daniel gives the following example of how to add section 
% numbers to the elements in the list of todos.
% The code is slightly modified from 
% \url{http://tex.stackexchange.com/questions/18838/replacing-page-number-with-other-counter-in-listoftodos}.
% An example of the modified list of todos is shown below, the complete 
% code example is given in the example directory.\\
% \noindent
% \begin{tikzpicture}
% \draw node[shape=rectangle, fill=black!30, inner sep=1mm]{\includegraphics[width=\linewidth-2mm]{img/AlteredAppearenceOfListOfTodos.png}};
% \end{tikzpicture}
% 
% 
% \subsubsection{Tikz externalization issues}
% 
% Using the tikz externalization framework together with todonotes 
% can lead to some problems.
% One solution is to disable the externalization just before the \verb!todo! 
% command is issued and then reactivate externalization afterwards.
% The \verb!ruggedtodo! handles this deactivation and reactivation.
% \begin{verbatim}
% \usetikzlibrary{external}
% \tikzexternalize
% \newcommand{\ruggedtodo}[2][]{\tikzexternaldisable\todo[#1]{#2}\tikzexternalenable}
% \end{verbatim}
% 
% 
% \subsubsection{Highligt text to fix}
% Tobias Winchen provides the following example on how to highlight
% text related to the inserted todonote.
% \makeatletter
% \if@todonotes@disabled
% \newcommand{\hlfix}[2]{#1}
% \else
% \newcommand{\hlfix}[2]{\texthl{#1}\todo{#2}}
% \fi
% \makeatother
% Example \hlfix{wrong text}{fix text}~continues here. 
% Notice that the code relies on the \verb!soul! package.
% \begin{verbatim}
% \makeatletter
% \if@todonotes@disabled
% \newcommand{\hlfix}[2]{#1}
% \else
% \newcommand{\hlfix}[2]{\texthl{#1}\todo{#2}}
% \fi
% \makeatother
% Example \hlfix{wrong text}{fix text}~continues here. 
% \end{verbatim}
