Summary 0000232: IMPLEMENTED: improved complex/real LU decomposition
Description Improvements:
* new level-3 ALGLIB BLAS is used (future improvements in ALGLIB BLAS will increase LU performance)
* cache-oblivious algorithm allows to obtain good performance without tuning for specific CPU
* automatic scaling (to avoid overflow when dealing with near-overflow matrices)

Other changes:
* CLU and LU units are merged, all code moved to TRFAC unit
