Returning eigenvalues from classical_mds? #60

Hello.
It would be very nice if classical_mds function returns not only the configuration matrix for a given distance matrix, but also the eigenvalues of the Gram matrix of the configurations, just like MATLAB's cmdscale function does. By examining those eigenvalues, we can see what would be a good embedding dimension for the classical MDS. It should be easy since inside classical_mds, those eigenvalues are computed anyways.
Thanks!
