//       Class : EggMorph
// Description : A single <Dxyz> or <Duv> or some such entry.  This
//               simply contains the morph name and the offset value.
//               The class EggMorph is actually a template class on
//               the type of value that is being offset; the specific
//               kinds of morphs are instantiated from this below.
