A way to kill things when controller seems to be stucked

[durringn]

Expected behaviour

We should be able to fill any layer with every kind of pattern. If not, the algorithm must be skipped in order to try something else. In other words, when a filling algorithms infinetely loop, there should be a way to nicely stop it.

Actual behaviour

It gets impossible to fill a given layer (whatever the pattern used) when the computation time for the algorithm gets infinite. There is no way to skip the calculations and to press any other button.

Steps to reproduce the error

Still to determinate

How to overcome the error

Skip and relaunch MeshInBits. better would be to simply restart controller upon click of a kind of stop button
