Example:
/Users/weppos/.rvm/gems/ruby-1.8.7-p330/gems/couchrest_model-1.0.0/lib/couchrest/model/associations.rb:29:in `belongs_to': Unable to convert class name into Constant for Document#dossier (RuntimeError)
although the real error is
/Users/weppos/Projects/working/.../app/models/user.rb:56: undefined method `validates_uniqueness_of' for User:Class (NoMethodError)
Refactored basic directory structure.
Moved to ActiveSupport for Validations and Callbacks.
Cleaned up older code, and removed support for text property types.
