Delegate method that will reduce the data. The method wil take in two data variables and reduce them to another data variable, resulting in a Log2(comm.Size) number of reductions when used in the communication reduction methods.

public delegate T ReductionOperation<T>(
	T left,
	T right
)

Public Delegate Function ReductionOperation(Of T) ( _
	left As T, _
	right As T _
) As T

generic<typename T>
