// Class Configuration
//
//  Encapsulates the control, access  and, persistence of user defined
//  settings for the wsjtx GUI.  Setting values are accessed through a
//  QDialog window containing concept orientated tab windows.
//
// Responsibilities
//
//  Provides management of  the CAT and PTT  rig interfaces, providing
//  control access  via a minimal generic  set of Qt slots  and status
//  updates via Qt signals.  Internally  the rig control capability is
//  farmed out  to a  separate thread  since many  of the  rig control
//  functions are blocking.
//
//  All user  settings required by  the wsjtx GUI are  exposed through
//  query methods.  Settings only become  visible once they  have been
//  accepted by the user which is  done by clicking the "OK" button on
//  the settings dialog.
//
//  The QSettings instance  passed to the constructor is  used to read
//  and write user settings.
//
//  Pointers to three QAbstractItemModel  objects are provided to give
//  access to amateur band  information, user working frequencies and,
//  user operating  band information.  These porovide  consistent data
//  models that can  be used in GUI lists or  tables or simply queried
//  for user defined bands, default operating frequencies and, station
//  descriptions.
