README 

With pro-STAR version v4, the input formats have changed radically.
  * Easier to parse space-delimited input formats
  * No arbitrary or integral couples
  * No trimmed or degenerate cells
  * Support for polyhedral cells
  * Boundaries are directly connected to cell and faces
  
Since the boundaries are now connected directly to the faces,
we now must be concerned with cell face notation otherwise we perform the
incorrect lookup. 
Fortunately, there are only 4 primitive shapes to be concerned with.

Hexa:
   Foam                  pro-STAR
   ~~~~~~~~~~~~~~        ~~~~~~~~~~~
   Face 0 (0 4 7 3)  ->  F5: (0 4 7 3)
   Face 1 (1 2 6 5)  ->  F6: (1 2 6 5)
   Face 2 (0 1 5 4)  ->  F3: (0 1 5 4)
   Face 3 (3 7 6 2)  ->  F4: (2 3 7 6)	
   Face 4 (0 3 2 1)  ->  F1: (0 3 2 1)
   Face 5 (4 5 6 7)  ->  F2: (4 5 6 7)
      
  
Prism:
   Foam                  pro-STAR
   ~~~~~~~~~~~~~~        ~~~~~~~~~~~
   Face 0 (0 2 1)    ->  F1: (0 2 1)
   Face 1 (3 4 5)    ->  F2: (3 4 5)
   Face 2 (0 3 5 2)  ->  F5: (0 3 5 2)
   Face 3 (1 2 5 4)  ->  F6: (1 2 5 4)
   Face 4 (0 1 4 3)  ->  F3: (0 1 4 3)


Tetra:
   Foam                  pro-STAR
   ~~~~~~~~~~~~~~        ~~~~~~~~~~~
   Face 0 (1 2 3)    ->  F6: (1 2 3)
   Face 1 (0 3 2)    ->  F5: (0 3 2)
   Face 2 (0 1 3)    ->  F3: (0 1 3)
   Face 3 (0 2 1)    ->  F1: (0 2 1)


Pyramid:
   Foam                  pro-STAR
   ~~~~~~~~~~~~~~        ~~~~~~~~~~~
   Face 0 (0 3 2 1)  ->  F1: (0 3 2 1)
   Face 1 (0 4 3)    ->  F5: (0 4 3)
   Face 2 (3 4 2)    ->  F4: (2 3 4)
   Face 3 (1 2 4)    ->  F6: (1 2 4)
   Face 4 (0 1 4)    ->  F3: (0 1 4)

Noting that several faces are skipped over in the pro-STAR definitions,
simply introducing a new cell modeller will be a problem.
Instead, subtract 1 from the pro-STAR faces and use lookup tables.
