'''Test program for 'minimum image convention' routines for triclinic cells

   This program is public domain.
   
   Author(s): Toon Verstraelen
   
   The minimum image convention (MIC) is a standard method in molecular
   simulations of periodic systems. The convention states that one can
   approximate the interaction between atom i and all periodic images of atom j
