* Returns the list of tModel keys possessing the keyedReferences in the passed category bag.
* Output is restricted by list of tModel keys passed in. If null, all tModels are searched.
* Output is produced by building the appropriate JPA query based on input and find qualifiers.

* From specification:
* "This is a list of category references. The returned tModelList contains tModelInfo elements whose
* associated tModels match all of the categories passed (logical AND by default). Specifying the
