Houdini Export and import Nodes tool

Houdini Export and import Node tool
my first useful tool for houdini . helps to speed up exporting and importing between student to commercial version .. pretty simple code and colorize nodes based on posfix string ....just put into your shelf !! and run it

posfix string :
emitter = EMITT
geometry = GEO
pyro_import = SIMOUT
lights = LGT
camera = cam
pyro_sim = SIM
sink object = SINK
pump object =PUMP
expansion object = EXP
collision obj = COLL
