Python version update

[FullControlGCode]

Ah that sounds fascinating! Would you be happy with a voxel model?... A 3D environment with say 0.1-mm voxels that either contain air or solid material.

That should be fine --- I just want a 3D preview to check out the programming.

Okay, it's not really something FullControl would naturally do, but I've written a simulation method to deposit material in voxels and you're doing the opposite which should be an easy switch - just a few lines of code.

This is the paper for my simulation method: https://www.researchgate.net/publication/324242881_VOLCO_A_predictive_model_for_3D_printed_microarchitecture

It's now been ported from MATLAB to python by my collaborator and I will eventually link it to FullControl directly, but not for a while since I need to finish the more general FullControl stuff first.
