c
c     "sizes.i" sets values for critical array dimensions used
c     throughout the software; these parameters will fix the size
c     of the largest systems that can be handled; values too large
c     for the computer memory or swap space to accomodate will
c     result in poor performance or outright failure
c
c     parameter:      maximum allowed number of:
c
c     maxatm          atoms in the molecular system
c     maxval          atoms directly bonded to an atom
c     maxgrp          user-defined groups of atoms
c     maxref          stored reference molecular systems
