// <synopsis>
// The EPointVisJonesMRec class allows the creation of records for the
// main calibration table of EPointVisJones type, and provides access
// to the individual record fields. Specializations for GJones, DJones,
// TJones and BJones calibration table records are provided through 
// inheritance.
