The functionDelaunayTriangulation of
DiscreteMath`ComputationalGeometry` returns an adjacency list. 

The function TriangularSurfacePlot (same package) requires as
input a triangle-by-triangle index list (list of 3 corners)

Question: is there a module that converts the adjacency list to the 
triangle index list?  I looked at the package and didnt see one that fits.
