The main script is CreateTracks.ncl

	There are a number of scripts that needs to be loaded 
	at the top of this this script. All these are located 
	in the src directory.

	The NCL gsn_code.ncl and gsn_csm_ncl script also needs
	to be loaded.

	There is a "CreateTracks.csh" that comes with the script. No need to
	run this, as the ncl script will call it if needed.
