TestCase that does not catch exceptions so you can debug them interactively

import unittest

"""
When you user code or assertions throw exceptions, default behavior is to aggregate and report these, calls to each test method are wrapped in try:.  When it is preferrable to handle these with a debugger and step back into frames of user code, this subclass this TestCase which uses .debug() rather then .run()
