    ant

To run:
    java  -jar jars/paralleltask.jar nThreads nDoubles mode \
                        balanced [size]
        nThreads - Size of the executor or fork/join pool
	nDoubles - Size of the double array
	mode - 0 for thread pool, 1 for fork/join pool
	unbalanced - false for the balanced test; true for the unbalanced test
	size - optional, size at which to switch from recursive fork/join
