New UiAutomator Tests for the ONCE UX plugin.

All tests save for LearnMoreCheck.java are in the planning stages. Any comments or suggestions about their execution or the concepts themselves would be greatly appreciated.
Nice to see so many comments but the pendulum may be swiinging too far.  I generally try to have one comment for about 5-10 lines of code.  I think of the comment as the "spec" for the code and the code as the "implementation" of the spec.  So if they are consistent, they are likely to be correct.
