Any opinion about this granularity? Another options for the direct
solvers would be to organize them into three modules:
DirectSparseCholesky, DirectSparseLU, DirectSparseQR.

I don't think it matters a lot, but I think a split in DirectSparseCholesky / DirectSparseLU / DirectSparseQR nicely mirrors the Cholesky / LU / QR split for dense matrices.
