Title: Added cost driven partitioner

Added the ability to perform cost driven partitioning of the join
matrix to the workers. This feature, along with good cost model, will
lead to join matrix partitions that will minimize the cost of the
theta-join. For the moment, the cost function used is:
1/(number-of-workers-used). This will force the partitioner to use
as many workers as made available.
