+   This is closely related to a crystla monochromator. A crystal monochromator
+   can be used to select a wavelength or an energy. In Sics these three things
+   are kept separate. The actual monochromator and its variables are dealt 
+   with in selector.*. This file contains prototypes for functions to deal
+   with Wavelength and Energy variables.
