# 2014.06.04 For hardcore XSI fans
# Original .mel idea by 'jimtheartist'
# Script converted to python and edited by Bravlin Pechatnik
# This script isn't convertor from one component selection filter to another with adjacent multiplication
# It's an alternative to selection filter. First function call would switch component mode, second one - apply adjacent multiplication
# Bind this pythone keys:
# AdjacentSelection.AdjacentVerts()
# AdjacentSelection.AdjacentEdges()
# AdjacentSelection.AdjacentFaces()
