Normalized cut now computes eigenvalues up to only a constant number iterations of the lanczos algorithm, for a tradeoff between performance and accuracy.
Merge branch 'kuwahara_filter' of https://github.com/alexisVallet/animation-character-identification into NormalizedCuts
Refqctoring, documentation, started implementing techniques to reduce the running time of the eigen solver for normalized cuts as described in the original paper - nearest neighbor graph with random pruning, working with the generalized eigenproblem, stopping recursion based on stability of the eigenvector.
