Watchable Object

Requirements

• when you create a new object and pass in a state, it must pass by copy not reference
• only single-level keys are supported

Patches

• whenever a change is made to the object's state, a patch object is created

• patch object signature: { rev: string, data: [ type(string), key(string), args:mixed ] }

• NOTE: patch.rev is the head revision of the entire object, at the point in time just prior to applying the patch (not the head revision of the object after applying the patch).
