 #### Color control
 
 Cell colors are chosen randomly (with a questionable rejection scheme). It
 might have been useful to input them along with sites coordinates, turning the
 application into a puzzling graphics engine.

 #### Site labelling
 
 The points are implicitly numbered in the order they were entered
 (starting at one). This can be overridden however, via a simple XSL
 transformation.
