---------------------------+------------------------------------------------
Improvements in the most recent versions:
* switched to LQUP instead of PLUQ for better performance
* because of this and other improvements much better handling of sparse-
ish matrices
* overall better performance for elimination
* better performance for mzd_transpose
* dropped the check for the numer of CPUs from configure which was
unused and not cross platform
* optional tuning code to calculate cache sizes (not enabled by default)
+ some refactoring
+ mzd_row_add_offset() fixed a segfault
