// <synopsis>
// An MVDouble is a simple Double, to be used in simple, single value
// Measures. Requirements can be found in the
// <linkto class=MeasValue>MeasValue</linkto> base class.<br>
// The only reasonable constructor is (but all MeasValue constructors are present)
// <src>MVDouble(Double)</src>; and an <src>operator Double</src> takes
// care of all other possibilities. Its external use is for
// <linkto class=MeasConvert>MeasConvert</linkto>, to distinguish between
// input in internal Measure units, and values which have to have
// units applied.
// </synopsis>
//
// <example>
// See e.g. <linkto class=MFrequency>MFrequency</linkto>
// </example>
//
// <motivation>
// To aid coordinate transformations possibilities
