27 Description
28  Takes the description of the block and the list of curved edges and
29  creates a list of points on edges together with the weighting factors
30 
31  For a given block, the correspondence between the ordering of vertex labels
32  and face labels is shown below. For vertex numbering in the sequence 0 to 7
33  (block, centre): faces 0 (f0) and 1 are left and right, respectively; faces
34  2 and 3 are front and back; and faces 4 and 5 are bottom and top:
