Multiple relation junction tables

[WanWizard]

It should be possible to use a junction table in more then one relation.

This means that in delete operations, this should be taken into account, as the junction table record should not be deleted when the relation between two objects is deleted (as other objects could depend on this relation).

This in turn means junction tables should probably be required to have their own model, so their relationships are known. This model can then be used as "through" model in a many-to-many relation.
