  // geometry entities when a composite is removed.  BWH - 11/09/05
  //
  // TODO - BWH - do we want to change the order now to make things simpler or come up
  // with a way to keep ids after removing composites
  //
  // TODO - BWH - the list functions in HiddenEntitySet are almost identical to the list functions in BridgeManager
  // the main difference is the order that entities are inserted.  If we want to make the behavior consistent, maybe a TBList class
  // could be implemented to use in both places.
