Tutte Code Version 0.9.12
-------------------------

The following updates have been made:

1) A long standing bug related to memory corruption has been fixed.

2) Support for 64bit machines now works correctly.  This means you can
   use very large caches (e.g. > 4G)

3) Removed the tutteviz component, since was causing a lot of
   compilation problems.

4) The "--split" option has been added.  This means you can split an
   input graph into a number of smaller graphs, which can then in turn
   be distributed over a grid.
