/*
  vector.H
  This is the vector.h provided by the Weiss text.  The only substantial
  change made is to remove the '#include vector.cpp' line at the end.

  Additionally, the name has been changed to .H from .h to meet the
  requirements of the course.

  Edit  1 Feb 2001  DLF for g++, include .C file
