testing pthread against thread clients
fixed tsp_pthread
added test for onely one thread
added less sync
migrated
now threadablel functions waiting and use yield
now evolute works with the waiting ad yoildting threadable functions
now init_ivs uses less sync
added comments for static function declatations
it seams that paralell access of memory slows down the evolution progress so that in some cases it is faster with onely one thread
