                                             model => $model,
                                             referenced_type_name => $ref_type,
                                             reverse_reference_name =>
                                                        $reverse_reference);

Usage   : $name = $ref->referenced_type_name();
Function: Returns the name of the type at the other end of this reference
Args    : none

Usage   : $cd = $ref->referenced_classdescriptor();
Function: Returns the ClassDescriptor of the other end of this reference
Args    : none

rev_referenced_classdescriptor

Function: Returns the ClassDescriptor of the other end of this reference
Args    : none

reverse_reference

Usage   : $ref = $ref->reverse_reference();
Function: Return the Reference object of the reverse reference
Args    : none

has_reverse_reference

Usage   : if ($ref->has_reverse_reference()) { ... }

Function: Return true if this is a collection and there is no reverse reference
Args    : none

is_one_to_many

Function: Return true if this is the collection end of a one-to-many relation,
          ie. this end is a collection and the other end is a reference
