Brian Damgaard, for a very friendly exchange over the fine details of the
Quicksort algorithm and its implementation in PDCLib, thanks.
+Rink Springer, for very precise bug reports including patches, and a heads-up
+on the capabilities of PDCLib when I most needed it, thanks.

Everyone involved in the first, "public" attempt at PDCLib, for bearing with me
when I restarted from scratch, thanks.
