Finding partition changes and copying memory moved to new functions.
Fixed up OpenMP version to account for newest changes.
Provisional setup for the Galois version (still uses Mutex)
Made initPartitions stop printing each partition's size.
Added a clearMemory function to ComputePartitions struct.
Apparently Galois keeps calling the destructor - can't put it there.
Switched Galois struct to use vector...
(llvm::SmallVector didn't help anyway).
TODO - run tests to compare the two...
Galois version (provisionally) finished w/ prints removed.
Added new data set and README to the test data sets.
