Methods
GetFacadingItems()
Implement this method to expose items that needs to be persisted.

Remarks
In order to figure out which objects taking part of the nested save operation that actually needs to be saved, this method allows for "fake id's" to be forced upon related objects. Upon receiving the "fake id", the objects receiving such an id can determine if they needs to be persisted (e.g. saved) to the database. However, the fake id's forced upon related objects must be set to correct id's in the OnIdUpdate method taking place later in the save operation.
OnPrimaryKeyRequestAsync(PKContainer)
Allow the object to add itself to a collection of requests for primary keys.
