Pronoid Android

• Note that my test code is in a different package from my app code.
  
• In related news, we call getInstrumentation().getTargetContext() to open our database, not, repeat not, getInstrumentation().getContext().
  
• And to call the button-push in "testSaveData()", we have to annotate that method as a "@UiThreadTest" method.
