Diffusion limited aggregation

DLA is a chemistry concept, it is usefull for undestand many system, such as electrodeposition, Hele-Shaw flow, mineral deposits, and dielectric breakdown. Here we start by create an array of point which will store cluster coordinate, then we put walkers/particles at random position around it and make them moove, when one of them is close enough from one of the cluster point, we add it to he cluster / tree.
