Capitalize Blimp

Done.

Make this protected?

Call it "QuitRunLoop"? This isn't finishing the test, either - the testing::Test
does that.

[haibinlu, 2016/05/03 19:32:43]

Done.

[Kevin M, 2016/05/02 21:32:40]

Put this before the overrides

[haibinlu, 2016/05/03 19:32:43]

Done.

[Kevin M, 2016/05/02 21:32:40]

This isn't running the test - it's running the product code :)

RunUntilQuit?

[haibinlu, 2016/05/03 19:32:43]

Done.
