/**
 * Table Definition for core_watch
 *
 * works with 'core_notify'
 *
 * any object can call
 *   $watch->notify($ontable, $onid)
 *
 *   in which case it should create a core_notify event.
 *
 *
 * Should 'event' trigger this..
 *   -> eg. somebody makes a 'EDIT' on 'person'
 *   -> a watch exists for
 *        ontable=person,
 *        onid = -1 <<-- every entry..
 *        person_id -> who is goes to.
 *        event = CRUD (eg. shortcut for edit/create/delete)
 *        medium = "REVIEW" << eg. review needed..
 *        
 *
