-Create takes a hash of values and creates a row in the database:
-
- 'Group' is the "top level" group we're building the cache for. This is an
- RT::Principal object
-
- 'Member' is the RT::Principal of the user or group we're adding
- to the cache.
-
- 'ImmediateParent' is the RT::Principal of the group that this principal
- belongs to to get here
-
- int(11) 'Via' is an internal reference to CachedGroupMembers->Id of
- the "parent" record of this cached group member. It should be empty if this
- member is a "direct" member of this group. (In that case, it will be set to this
- cached group member's id after creation)
-
- This routine should _only_ be called by GroupMember->Create
