affinefit - Produce a reg file defining an affine transformation fit
This program solves for the best fit of the control points to an
affine transformation.  The six coefficients are output to a "reg"
file that can be used in programs that project from level1 space to
level 2 space, such as last2prj.

The fit equations are

     newline  =  line_translation + line_coef1*line + line_coef2*sample
     newsample  =  sample_translation + samp_coef1*line + samp_coef2*sample

ADDITIONAL NOTES:

Parm	Description
FROM	Input cube file name. If the file extension is omitted, then ".cub" will be assumed.
FROMT	Input truth cube file name. If the file extension is omitted, then ".cub" will be assumed.
CFILE	CFILE is the ascii control point file which was created by COREGPR2, or some other program, or by the user by manually editing a file. There must be at least 6 control points in this file. This file must be in the following format (I5,4F10.0): point number, input line, input samp, truth line, truth samp EX: 1,10,1,15,30
OPTION	The affine transformation that is fit to the data can be a FULL affine (default), or TRANONLY (translation only).
