Sparse Cholesky in 80 lines that certainly would be interesting!

Don't feel disheartened! Although many people are actively involved with uBLAS
there are on a couple who can make such commits. It is also always good to
have a second opinion on such changes. For myself I was also wondering if the
fix should prompt the documentation to be improved with regard to how
compressed_matrix is internally manipulated.

Have a good weekend also!
