Add project TriangleAppUnitTesting; Android requires a separate project
specialized for unit testing; TriangleAppUnitTesting is specifically
linked to TriangleApp.
Add first functional test, deliberately fail test.
Android application runs and main screen loads
...
Added MainActivityTests class for MainActivity unit tests
Add first MainActivity unit test: test_canGetInitialText; deliberately
fail test.
Can get the object displaying the initial text. TODO: replace the text
to display our own message.
Added Comments to help understand Android
