// Note:
// LBMLBTRMFrameEntry, LBMLBTRMSQNEntry, LBMLBTRMNCFReasonEntry, LBMLBTRMNCFSQNEntry, LBMLBTRMSourceTransportEntry, LBMLBTRMSourceEntry,
// LBMLBTRMReceiverTransportEntry, and LBMLBTRMReceiverEntry are all derived from  a QTreeWidgetItem. Each instantiation can exist
// in two places: in a QTreeWidget, and in a containing QMap.
//
// For example:
// - LBMLBTRMTransportDialogInfo contains a QMap of the sources (LBMLBTRMSourceEntry) and receivers (LBMLBTRMReceiverEntry)
// - A source (LBMLBTRMSourceEntry) contains a QMap of the source transports originating from it (LBMLBTRMSourceTransportEntry)
// - A source transport (LBMLBTRMSourceTransportEntry) contains QMaps of data, RX data, and SM SQNs (LBMLBTRMSQNEntry) and NCF SQNs
//   (LBMLBTRMNCFSQNEntry)
// - A data SQN (LBMLBTRMSQNEntry) contains a QMap of the frames (LBMLBTRMFrameEntry) in which that SQN appears
//
// Not all of the entries actually appear in a QTreeWidget at one time. For example, in the source details, if no specific source
// transport is selected, nothing is in the source details tree. If Data SQNs is selected, then those details appear in the source
// details tree. Switching to RX Data SQNs removes whatever is currently in the source details tree, and adds the RX details for
// the selected transport.
//
// The actual owner of one of the above QTreeWidgetItem-derived items is the QMap container in its parent. The item is "loaned" to
// the QTreeWidget for display.
//
// All of this is to explain why
// 1) we are frequently adding things to a QTreeWidget
// 2) things are removed (takeTopLevelItem) from a QTreeWidget
// 3) destruction involves removing all items from all QTreeWidgets (rather than letting QTreeWidget delete them)
// 4) the destructor for each item has the form
//    <for each QMap container>
//      for (XXXMapIterator it = m_xxx.begin(); it != m_xxx.end(); it++)
//      {
//          delete *it;
//      }
//      m_xxx.clear();
//    The for-loop calls the destructor for each item, while the clear() cleans up the space used by the QMap itself.
