Backbone.Collection) lacked some of the
capabilities available to models and views. It wasn't possible to
provide typed custom options, for example. There were also some mistakes

This change introduces new generics when subclassing
allowing an interface to be provided for custom options. This mixes into

properly with the instance as
The default model type for collections is also now

Unit tests have been added to test all static attribute/function
behavior. Since our testing uses TypeScript, the type-related issues
were also caught by tests.
Unit tests pass.
