Detailed Description

An implementation of the Anasazi::MatOrthoManager that performs
orthogonalization using the SVQB iterative orthogonalization technique
described by Stathapoulos and Wu. This orthogonalization routine,
while not returning the upper triangular factors of the popular Gram-
Schmidt method, has a communication cost (measured in number of
communication calls) that is independent of the number of columns in
the basis.

This method computes the error in orthogonality of two multivectors,
measured as the Frobenius norm of innerProd(X,Y). The method has the
option of exploiting a caller-provided MX.
