Bug 192516: Moving the loose .pm files into the Bugzilla directory, where they belong. These files pre-date the Bugzilla directory, and would have gone there had it existed at the time. The four files in question were copied on the CVS server to preserve CVS history in the files. This checkin deletes them from the old location and modifies everything else to know where they are now.

-# This object models a set of relations between one item and a group
-# of other items. An example is the set of relations between one bug
-# and the users CCed on that bug. Currently, the relation objects are
-# expected to be bugzilla userids. However, this could and perhaps
-# should be generalized to work with non userid objects, such as
-# keywords associated with a bug. That shouldn't be hard to do; it
-# might involve turning this into a virtual base class, and having
-# UserSet and KeywordSet types that inherit from it.
