Summary 0000606: QQP improvements
Description * Newton step for sparse QP with general linear constraints
* investigate feasibility of updating Cholesky decomposition for sparse QP problems. It is possible, but sometimes it is faster to perform sparse Cholesky from scratch than to update it. At least, for large batches of updates...
* permutation of variables (should be performed during initial scaling of the problem) for faster sparse Cholesky
* support for sparse Cholesky solvers other than SKS-based one
