		const Vector< long long > &	a_computeLoads,
		const Vector< Box > &	a_boxes,

convenience function to load balance a Vector of Loads based on load. boxes also passed in for possible use with box-swapping code

		const Vector< long int > &	a_computeLoads,

Accepts "long int" computeLoads and then just calls the "long long" version.

convenience function to gather a distributed set of Boxes with their corresponding processor assignment

Assumption is that each processor has at most one valid box. This is useful when interacting with other distributed codes which might not have the entire set of distributed boxes on all processors.
