Path: Fix simulator bug workaround while milling curves with small radius.

Browse Source 
Path Simulator produces out of trace artifacts while milling curves with small radius.
In VolSim.cpp the branch for curve radius smaller then tool radius is not implemented yet.
In this condition the simulator produces artifacts of higher radius while milling path using G2 or G3.
There is an implementation of G2 and G3 in python level.
