3.3.- Parallel_stable_sort

This is an adaptation of the Samplesort algorithm, using an additional memory a half of the memory used by the data (the original algorithm uses an additional memory as the used by the data).

It is a highly efficient parallel stable sort, optimized for use with many threads.
