[wip] added clusters of particles to the system
Particles can be assigned to a group
Groups have unique attraction/repulsion settings with other groups
(Jeffrey Ventrella)
For now groups are randomly assigned to organisms particles, next step will be to control these groups (as well as other behaviours) using the graph rewriting growth.
I'm so excited by this development, one of my issues with the raw clusters system was the lack of stability of emerging structuresβusing spring forces seems to fix it.
