Add 3 empty lines and then also add documentation for this function.

Do you even still need mp_matrix in that case?

I have tried address the changes above (except removing the mp_matrix - will get to it). Probably not clear from the rebase, sorry. Do not review quite yet. |

We typically have 3 empty lines between top-level constructs. So take one off again here.

This implementation applies (BC^{-1}B^T)^{-1}) by creating an operator that applies B^T, followed by C^{-1},
followed by B, then doing a CG solve with this new operator.
