       extposition - get list of position numbers for axoneme doublets


       This program produces a list of position numbers for portions of images
       extracted by the program Extstack.  It is a quick hack of that program.
       It requires the two point files used by Extstack, the reference point
       file and the extraction point file.  In addition, it requires a file of
       points specifying the location of position 1 on whichever sections that
       can be determined.  Also, one must specify whether position numbers
       increase in the counter-clockwise or clockwise direction.

       If there is a position 1 point for a particular section, then the pro-
       gram assigns appropriate position numbers to all of the extraction
       points on that section; otherwise it assigns a position number of zero.
