Algorithm

Check that the number of files in the input image list is 4- if not abort with
an appropriate error message.

For each input image:

1) Check that BINBPE is set to TRUE.

2) Check that the WINDOWDX value is 512.

3) Check that the WINDOWX0 value is either 0, 512, 1024 OR 1536.      

4) Check that this WINDOWX0 value is not identical to one of the previous values.

5) Check that the WINDOWY0 value is 0.

6) Check that the WINDOWDY value is 2048.

If any of the above checks fail, abort with an appropriate message. 

Combine the 4 images into a single image.
Create the output file, write the image to the file and add the
appropriate keywords.
