Initial commit
Initial commit of the hitran.py module code.
Added par file folder to repo.
Updated README with warning on repo size.
Modified code to automatically unzip ZIP files.\n\nSince GitHub places a limit on the allowed sizes of files, and some of the HITRAN data files were larger than this limit, I zipped them up to fit. This update to the code thus allows the 'read_hitran2012_parfile()' function to accept zip filename arguments.
Updated README file.
