This reverts commit b11928ed.

Fix for #157

Replacing old block with new one.

fix overwriting of namespaced model test annotations with non-namespaced model annotations

migrate.rake should live in lib/tasks

changing to get rid of deprecation warnings

the special-purpose file resolution method for test/spec files was failing
with namespaced test files (ex. User model attributes would annotate both
test/unit/user_test.rb as well as test/unit/foo/user_test.rb, instead of
only the former)

Fixed gemspec files attribute

Always load models, since they may not be autoloaded by Rails

Refactor initialization of exclude options

* update option parser
* didn't add tests b/c i'm not using rvm and can't see an easy way to add commandline option parsing tests

Use RDoc inline-code formatting
