Bug, feature request, or proposal:

Bug

What is the expected behavior?

It should have an option to align buttons vertically

What is the current behavior?

Error:

"Template parse errors:
Can't bind to 'vertical' since it isn't a known property of 'md-button-toggle-group'.

1. If 'md-button-toggle-group' is an Angular component and it has 'vertical' input, then verify that it is part of this module.
2. If 'md-button-toggle-group' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message.
   ("denav #sidenav mode="side" class="app-sidenav">

<md-button-toggle-group name="alignment" [ERROR ->]vertical="{{isVertical}}">
format_align_left</"): AppComponent@6:43"

What is the use-case or motivation for changing an existing behavior?

It should be done according issue #1892

Which versions of Angular, Material, OS, browsers are affected?

"@angular/core": "~2.2.0",
"@angular/material": "^2.0.0-alpha.10",

Sorry, I suppose it will be in next release.
