Changelog
--------

4.7.1999    Joonas: I did set up the basic directory structure: Makefile,
            README, Changes, main.c, image loading, doc/index.html, TODO, 
	    argument parsing..

5.7.1999    Joonas: Debugged PGM loading routines, added some skeleton to
            main(), wrote line-drawing to ease the generation of result.

            Joshua(Jozsef):I wrote the path_coding routin,but I didn't test
            it.Maybe tomorow... Makefile has also changed: we have to link 
	    the math library.     

6.7.1999    Joonas: Wrote a line thinning algorithm and coastline-walking 
            algorithm to find the end of the coastline (both in clear_map).
	    Also wrote the coordinate list creation function.

            Joshua(Jozsef): Testing and debugging the path_coding routine.
	    For some reason, the it seems to turn cw all the time

7.7.1999    Joonas: Wrote some help routines for the error calculation: step, 
	    euclidian distance, pedestrian distance. Modified the line-
	    drawing to clip the lines. Wrote debugging code for joshuas
 	    path_coding.

8.7.1999    Joonas: Rewrote the Joshuas path coding routine, but 
            it seems that Joshua did got his routine ready faster ;)
	    Wrote brute force searching algorithm. Started to reimplement
	    the nmc:s part of the project.
	    
	    Joshua: Completed the debugging of pathcoding ! :) 

9.7.1999    Joonas: Rewrote all the error_calculation code, did test-
	    images, got basically everything working ! Matching works,
  	    but is quite slow. Made it better using inverse matching and
	    two-phase searching. Debugged invert_path. Debugged path coding.
