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