A constant library has been added with physical constants that can be accessed
by name or alias with the constant function. The search_constants function
with no argument gives a listing of all built-in constants. Each constant
definition includes any correlations with other constants.
The Quantity class has been added to represent a general numerical value
multiplied by a unit and the unit function has been added to retrieve
Unit instances from the unit library by name or alias. Unit instances
can now be multiplied and divided by other Unit instances to produce
composite units, can be multiplied and divided by numbers to produce
Quantity instances or multiply or divide Quantity instances. The
gummy class is now a subclass of Quantity with a nummy value rather
than a subclass of nummy. A QuantityArray class has been introduced
to represent an array of values all with the same unit. Multiplying a Unit
instance by a list, tuple, or numpy array produces a QuantityArray instance.
The immy class has been introduced as an ummy valued counterpart of the
jummy class for representing complex values with uncertainties. immy
and jummy values can now be displayed in a polar representation in addition
to a cartesian representation. immy and jummy .r and .phi properties
have been added to access the magnitude and argument of the values as a
complement to the .real and .imag properties.
