> Cayenne Modeler should issue a warning when you have the To-Many checkbox checked on
both sides of a relationship in the DbEntity section.  When the checkbox is selected on both
sides, which isn't a valid combination, Cayenne gets confused and can insert NULLs for FKs
and orphan records.

> Also, Cayenne Modeler should issue a warning when both sides of the relationship are
to-one (assuming To-Dependent PK isn't checked).
