------------
This is mostly a file bookkeeping routine for the cosmic ray rejection task.
It takes care of input/output files open/close, check for dimensions, read/

---- ------ -----------
06-May-1996 J.-C. Hsu Adapt from the SPP code crrej_do.x
05-Aug-1998 W. Hack Modified to handle ACS data
11-Feb-1999 W. Hack EXPTIME now in Pri. Hdr.
18-Mar-1999 W.J. Hack Revised to read EXPTIMEs from Primary headers
for cr_scaling using tpin directly
14-Sep-1999 W.J. Hack Cleaned up SHADCORR usage. Added check for max
