    function s = guid(h, pSub)
%GUID Return globally unique identifier 
%
%  STR = GUID(NODE, pSUB) returns a string that uniquely identifies this
%  node's browser view.  pSUB is a pointer to the sub item that the view
%  will be displaying.  If pSUB is omitted it is assumed that this is
%  equivalent to pSUB being a null xregpointer.
%
%  NODE = GUID(NODE, STR) sets a new guid string in the node object
