;NAME:
;	WNODE
;
;PURPOSE:
;	To perform tree indexing.

;
;CALLING SEQUENCE:
;	index = WNODE(d,b)
;
;INPUTS:
;    d  =   depth from root of tree 
;    b  =   index among the 2^d possibilities 
;          in a left-right scan at that depth 
;
;OUTPUTS:
;    index  =  linear index of node in tree structure
