Should there be a unit test for this file?

[Michael Courage, 2013/03/27 18:40:11]

Pretty much everything in this file would have to be stubbed out for a test, so
I think the answer is no.

This implies to me that the signin flow object should only be used once, we
should never call Start a second time.  Let's add that limitation to the .h file
description.

[Michael Courage, 2013/03/27 18:40:11]

Done.
