Creates a mapping for each object in the collection for which such a mapping is possible.

Creates a mapping for each object in the collection where such a mapping is possible. All of the iteration is performed here and the matching can be affected by changing ShouldInclude(IDatabaseObject, IDatabaseObject, Object) in the sub class. The main action of joining to objects together is performed by Join(IDatabaseObject, IDatabaseObject) which can itself call CreateMappings on child database objects.
