c ========================================

This is a collisionally dominated H2 simulation.  The temperature
has been fixed at 2000K and the large molecule turned on.  The calculation
checks the returned value of the ortho to para densities.
Cosmic rays and the incident continuum have little effect, the density is high,
so the populations should be close to LTE.
