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's memory and/or swap space to accomodate
c     will 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
