DataModelWave < IVOA

---+ Wave

Probably an overkill way of modelling wavelength/frequency, but allows us to model it without worrying about which to use.

---++ Interface 

The published properties would be:

   * =Frequency= : Hz (real)
   * =Wavelength= : meters (real) 

   * [[DataModelAccuracy][ =Accuracy= ]] 

   * =Ucd= - I think

---++ Implementation

This looks like a very simple object.  Obviously we don't need to store both Frequency and Wavelength internally. 

I think it makes sense for a Wave to be immutable (ie it can only be created with a set of characteristics, and thereafter is 'readonly'). The properties are all interdependent, so changing one without the other does not make sense.
