#Purpose: To organise FITS files such that they all have the extension fit and reader the header to create
#         lists of bias, dark and target frames. Eventually this is to link into pyphot.
#         http://www.krioma.net/pyphot.php
#Usage of the works is permitted provided that this instrument is retained with the works, so that any entity that uses the works is notified of this instrument.
#DISCLAIMER: THE WORKS ARE WITHOUT WARRANTY.  
#Notes:	  Might need to change the cut character values depending on different headers 
#         (this is for the Wast Hills Apogee camera data)
#Mod 19-10-09: added the loop instead of listing the output.
