FEATURE: Copyable simple sample test

[stevebuik]

When creating a new test, it takes a bit of time to create the new app, then copy in and clean up the code from greased_LoginFormTests.

A better solution would be another sample which has two test components, one focus change and one example of every test.xxx feature in the tool. This would optimise for minimum time for a developer to create a new test.

The test can be a test for ui:inputText so that there is some state that can be changed and asserted.
