pfsearchV3

The new pfsearchV3 program replaces the original pfsearch program distributed with the pftools. It uses modern CPU instructions to exploit the capabilities of multicore processors and a new heuristic filter to rapidly score and select possible candidate matches. On a modern dual-threaded 8 cores computer these improvements increase the speed of pfsearch by 2 orders of magnitude.
