/*
HOW TO SEE DEBUG LINES FROM YOUR UNIT TESTS:

1. set a line like this at the start of your test:
           org.robolectric.shadows.ShadowLog.stream = System.err;
2. run the tests from the command line
3. Look at the test report file in your web browser, e.g.
   file:///Users/dyoung/workspace/AndroidProximityLibrary/build/reports/tests/index.html
4. Expand the System.err section
