* Small change to SetupAndTeardown#teardown_stubs suggested by Luke Redpath (http://www.lukeredpath.co.uk) to allow use of Stubba with RSpec (http://rspec.rubyforge.org).
* Reorganized directory structure and extracted addition of setup and teardown methods into SmartTestCase mini-library.
* Addition of auto-verify for Mocha (but not Stubba). This means there is more significance in the choice of expects or stubs in that any expects on a mock will automatically get verified.
