Interface to Anasazi to eigen-computations.

This function creates an interface from an Epetra_RowMatrix and Anasazi. Parameters are specified using a Teuchos parameters list.

Parameters:
\in RowMatrix: Epetra_RowMatrix;
\out EigenVectors: Epetra_MultiVectors, that will contain the requested eigenvectors;
\out RealEigenvalues: double array that will contain the real part of the computed eigenvalues;
\out ImagEigenvalues: double array that will contain the imaginary part of the computed eigenvalues;
\in List: Teuchos parameters' list containing the required options.
