The program now searches through the 8 neighbours of a diffusing particle and checks if the diffusing particle has found the aggregate. The aggregate is also coloured for aesthetics.

The diffusion dynamics are not physical as two diffusing particles may hop to the same site. Currently the
each grid point stores a bool (true for aggregate particles, false otherwise). In order that the diffusion
mechanism might be made more physically realistic the grid would have to be made more generally into a spin
model. This would allow for the following

0 - site, 1 - diffusing particle, 2 - aggregate.

In future work I will improve this. Also I will make a grid which can store floats representing composition
this would allow me to do some spinodal decomposition simulations.
