PDME — IDL consistency Issue for PDM

Summary: In the Salt Lake city meeting Ed brought up a point that Revisions
cannot be created independent of the Master and the Iteration cannot
be created independent of the Revision to which it belongs.

As a result the Factory for the Master - to - Revision relationship
does not exit and the create function for the revision takes the
Master as a parameter and also creates the MasterRevision
relationship. The same is also true for Revision to Iteration
Relationship. eg BaselineRevisionFactory - The create function takes a
BaselineMaster as a parameter and creates the
BaselineMasterComposition Relationship.

This behaviour has been duplicated in the Master-Revision-Iteration
relationships of most of the modules expect the Product Structure
Definition. In the ProductStructureDefinition Module the following
relationships should not have factories:
PartMasterComposition
PartDataRelationship
PartStructureRelationship
PartDataIterationRelationship
PartStructureIterationRelationship

Taking this principle one step further we can say that this behaviour
is true for all Containment Type of relationships (Black Diamond). If
so then there are a few other places where this applies these are
Change Management Module:
Deliverable relationship
ChangeDescription relationship
