Added RadiationFieldType = 15 for optically thin HM12 photo-ionization/heating rates. New code reads in the tabulated values and interpolates them during the calculate rates routine. I've updated a bit of the documentation too. This is my first pull request so please let me know if I should do anything else here.
** Update: removed a personal makefile and merged new changes in the meantime. Still learning hg so I hope I did this correctly
Thanks for submitting your contributions. I can't speak to the bulk of this, but one thing I see is that you've included the makefile for your laptop. Generally we only bundle makefiles for clusters, not personal makefiles. You might find the .enzo folder (described here: https://enzo.readthedocs.org/en/latest/tutorials/building_enzo.html#porting) useful to track personal makefiles without checking them into version control.
Hi Nathan, thanks for pointing me to the .enzo folder. I didn't mean for the laptop makefile to go into the pull request. I've removed it. When I tried to push the change hg asked me to pull first and then merge so I've done that as well. Hopefully I did things correctly!
