  Header File:  String Array.H

  This provides a relatively simple C++ class for manipulating an array of
  character strings.  In this project, we use it for lists of associated
  devices, or potential associated devices, etc.  I'm not currently sorting
  this list.

  The class declaration may look a bit bizarre.  Since most of the arrays
  will in fact be rather small, I picked a decent size.  When they get bigger,
  I'll chain them internally and use recursion to perform any needed function.
