;make last_minus_first
;
;PURPOSE:
;  To create a .fits file consisting of only the last minus first read.
;  This deals with the large files that ds9 cannot handle
;KEYWORDS:
;  MKJPG - if set, a .tif image will be generated that has the 
;            coordinates, XStartJPG, XStopJPG, YStartJPG, YStopJPG
;  MKSLDSHW - if set, a 10 image slide sequence of reads will be output
;	      in .tif format
;  VERTICAL - if set, the slideshow will be vertical rather than horizontal
;  NUMSEQ   - the number of slides to put in the image.  They will be distributed
;	      uniformly in time throughout the ramp
