Summary of changes
- Added the following methods to persistence/mongoid_persistence.rb
- find_in_state
- count_in_state
- with_state_scope (protected in AR, would argue it should be made public there.
- I did not port calculate_in_state, due to AR vs. Mongoid API differences; I made with_state_scope public instead. (I think it should be public for AR as well.)
- Moved AASM::Base patch which aliases scopes in persistence/active_record_persistence.rb to persistence/base.rb, and added a Mongoid detection clause to the if statement (in addition to AR). Also deleted commented code from the original method.
- Added 'mongoid' as dev dependency to gemspec
- Created two test files (mongoid_persistance_spec.rb and mongoid_models.rb) covering all my changes.
