This script unwelds faces from one or several selected vertex/vertices.
Usage:
In edit mode Select at least one vertex, then run this script.
The options are:
- unbind points;<br>
a new point is added to each face connected to the selected one.
- with noise;<br>
the new points location is varied with noise
- middle face;<br>
the new point is located at the center of face to which it is connected

# Changelog
#----------------------------------------------
# 25/05 :
# -- separate choice, normal (same place) or spread at random, middle of the face
# -- works on several vertices too
# -- Quite vertex bevelling on <<lone>> vertex : create hole in faces around this
# vertex
# 03/06 :
# -- a sort of "bevelled vertex" extrusion controled by horizontal mouse
# displacement. just a beta test to the mouse control.
# 08/08 :
# -- minor correction to completely disconnect face.

# -- sommets multiples /
# -- presque unvertex bevelling sur un vertex solitaire : cree

# 03/06 :
# -- une sorte de vertex extruder en biseau, controle par
