Summary: 0000231: IMPLEMENTED: improved real/Hermitian Cholesky decomposition
Description: Improved Cholesky decomposition:
* uses ALGLIB BLAS (future improvements in ALGLIB BLAS will improve Cholesky performance)
* implemented in cache-oblivious manner: performance (measured in FLOPS) GROWS with matrix size; no tuning for specific CPU is required to obtain good performance.

Other changes:
* CHOLESKY and HCHOLESKY units are merged with TRFAC unit
