title: Tool for path finding algorithm testing
body: <p>Anyone know, some tool for path finding algorithm testing.
  Where i could test my own writed path finding algorithm on 2d grid.
  Something like this <a href="http://topfat.blogspot.com/" rel="nofollow">http://topfat.blogspot.com/</a>
  But where i could write and run my own algorithms.
  It could be using any programming language.
  I can adjust my code almost to any programming language.</p>
