Invalidate the timetable having the specified timetableName in this timetable cache, and remove it from the cache. If a timetable having timetableName is not present in this cache, this method has no effect. Return the number of timetables that were invalidated. Note that a timetable that has been invalidated in the cache remains valid to all outstanding references to it, obtained via earlier calls to the getTimetable and lookupTimetable methods, until all of those references have been destroyed.
