changed number of RCR workers to matchooo workers. The new speed up is either 13x or 6x...... 13x is running the single version but for some odd reason, it garbage collects... the 6x comes from running the rcrpointer version with depth of 0 which SHOULD call no traverser and spawn no sese (other than the parent).
I think it could be faster still, but a bug in the conflict graph is preventing me from adding more seses to speed things up.

voronoi benchmark. On dc-11, the computation part runs 3x faster with a computation depth of 3.
It could probably do better but for some reason, when I add another sese (see Vertex.java line 115 where it's commented out), RuntimeConflictResolver.java crashes on line 506 (cannot find a conflict graph for a given sese).
