   	A mock database class.  All models should inherit from mdb.MockModel
   		
   		mdb.Get<T>(Guid id)
   		 - Returns the model with an id matching 'id' from the mock database
   		
   		mdb.All<T>()
   		 - Returns all models of type 'T' from the mock database
   		
   		mdb.Put(T model)
   		 - Saves (creates or updates) 'model' to the mock database
   		
   		mdb.Del(T model)
   		 - Deletes 'model' from the mock database
   		
   		mdb.Del(Guid id)
   		 - Deletes the model with 'id' from the mock database
   		
   		model.put()
   	  	 - Saves (creates or updates) 'model' to the mock database (alias for mdb.Put)
   		
   		model.del()
   		 - Deletes 'model' object from the mock database (alias for mdb.Del)
