 * Text file reading functions are static so they can be called from elewhere.
 * 
 * 17    11/18/97 8:10p Rwyatt
 * Will only load version 2.01 files.
 * Asserts that hash ID of material types are correct

 * Version number has gone to 2.01 because attenuation is now in dBs and not distance. The
 * loader will convert the old format to the new.

 * Calling save with a null name will save over the COL file last loaded. It will assert if no
 * file has been loaded. This is for the save  materials menu option in the GUIApp.
