Global variables

The name in curved brackets ${TempPath} represents a global variable.
Global variables can be used inside a node code and parameters.
(e.g. "textures/myEnvironment.${TEX}" will be "textures/myEnvironment.slo" for PRman
and "textures/myEnvironment.tdl for 3Delight")
The list of used global variables is defined inside global_vars.py.
