Subclasses must overload this method, which performs the actual operations.
The methods should first do a reinterpret cast of the arrays to the type suggested by datatype
(which will be one of the VTK type identifiers like VTK_INT, etc.). Both arrays are considered top be length entries. The method should perform the operation A*B (where * is a placeholder for whatever operation is actually performed) and store the result in B. The operation is assumed to be associative. Commutativity is specified by the Commutative method.

Subclasses override this method to specify whether their operation is commutative.
It should return 1 if commutative or 0 if not.
