CONSTRAINTS-OF
==============

syntax: (constraints-of <constraint-pattern-specifier>
                        [:IDENTIFIER T | NIL | Var]
                        [:KB <kb>])

Warning: yet not implemented!

This Function returns a list with the constraints of
the constraint pattern. If you do not give details,
then you will get back the objects and ':IDENTIFIER'
will be set to NIL, otherwise you will get back a
list of constraint identifiers.

example: >(constraint-of calculate-real-costs
                         :identifier T)
         (calculate-costs-for-clients)
