-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.

-# 25/05 :
-# -- separation du choix, normal ou dispersion hasardeuse,
-# milieu de face
-# -- sommets multiples /
-# -- presque unvertex bevelling sur un vertex solitaire : cree
-# un trou dans la facette autour du sommet
-# 03/06 :
-# -- une sorte de vertex extruder en biseau, controle par
-# movement horizontal de la souris
-# 08/08 :
-# -- correction mineure pour s'assurer que les faces soient
-# entierment deconnectees
