Detailed Description

An adaptor that supplies the operator interface to a multi-vector.

Supplies the operator interface for the operator C = op(A)*B where A, B, and C are multi-vectors, and op() is the identity or transpose operator. The convention is when the transpose is not requested, A is treated as a row-oriented multi-vector and therefore the domain map is the map of A. The corresponding range map is a local map of size given by the number of vectors When the transpose is selected, these are reversed.

This should really live somewhere else as it has nothing to do with Stokhos.
