Remove event bubbling functionality for nested collections/models. Was too hacky, and didn't handle cycles in the model/collection graph.
Rename all attribute classes to not have the suffix 'Attribute'. They are already in the 'attribute' package.
Add optional define() call for AMD loaders. Browser global still defined.
gitignore docs directory for now.
Fix a few documentation warnings.
Add latest Class.js (0.3.2)
Convert project to use RequireJS. Remove build process for now (need to implement RequireJS optimizer).
