Log Message:
Added optional DEPENDENT ON clause to WITH...COMPUTE statements that makes
the variables computed depdendent on a list of other attributees.
Specifically, if any of the other attributes are changed (by setting them,
NOT by recalculation), the computed variables will be dropped from the
cache, forcing them to be recalculated the next time they are accessed.
(Based on Steve Alexander's suggestion for an  "INVALIDATE FOR" clause.)
