//
// <synopsis>
// MeasRef specifies the reference frame for a physical quantity
// specified by one of the derived <linkto class=Measure>Measure</linkto>
// classes (e.g. <linkto class=MEpoch>MEpoch</linkto>). It is derived from
// <linkto class=MRBase>MRBase</linkto>, which describes the class.
//
// MeasRef containres are created using the <src>Measure::Ref</src> class
// (e.g. <src>MDirection::Ref</src>).
// </synopsis>
//
// <example>
// See <linkto class=Measure>Measure</linkto> for an example
// </example>
//
// <motivation>
// To gather all reference frame information in the one class.
