class Eigenvalue extends Eigen with Error

The Eigenvalue class is used to find the eigenvalues of an 'n' by 'n' matrix 'a' using an iterative technique that applies similarity transformations to convert 'a' into an upper triangular matrix, so that the eigenvalues appear along the diagonal. To improve performance, the 'a' matrix is first reduced to Hessenburg form. During the iterative steps, a shifted 'QR' decomposition is performed. Caveats: (1) it will not handle eigenvalues that are complex numbers, (2) it uses a simple shifting strategy that may slow convergence.
