Class DS.InternalModel

InternalModel is the Model class that we use internally inside Ember Data to represent models. Internal ED methods should only deal with InternalModel objects. It is a fast, plain Javascript class.

We expose DS.Model to application code, by materializing a DS.Model from InternalModel lazily, as a performance optimization.

InternalModel should never be exposed to application code. At the boundaries of the system, in places like find, push, etc. we convert between Models and InternalModels.

We need to make sure that the properties from InternalModel are correctly exposed/proxied on Model if they are needed.

If the adapter did not return a hash in response to a commit, merge the changed attributes and relationships into the existing saved data.
