This script unwelds faces from a selected vertex.
There's also experimental support for static or dynamic (move mouse

Usage:
Select a vertex, then run this script. Its options are:
- unbind points;<br>

- middle face;<br>
- static bevel vertex;<br>
- moving bevel vertex;

# Changelog
#----------------------------------------------
# 25/05 :
# -- separate choise, 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.
