Accessiblity

This library includes several accessibility related methods.
The SetNextFocus methods allow you to explicitly set the focus order. This order is important when the user navigates your
application with a directional controller (such as D-Pad).
SetContentDescription sets the content that will be used by accessibility services such as TalkBack to describe the interface.
