CEL in Parameters

Parameters that contain CEL expressions are set like any other string parameter only the value of the parameter is evaluated to a CEL expression. For example create a CEL expression on a CollectionCreate node that sets to the /root/geo location:

TIME = 0
root = NodegraphAPI.GetRootNode()
collection = NodegraphAPI.CreateNode( 'CollectionCreate',\
    root)
c = collection.getParameter( 'CEL' )
c.setValue( "( (/root/geo) )", TIME )
