- new concurrent score map using atom operation from java concurrency classes - redesigned difference beween StaticScore and Dynamic Score into ScoreMap and ReversibleScoreMap allowed that many classes can now use simple ScoreMap Objects which can be used better in concurrent environments using the ConcurrentScoreMap - switched from DynamicScore to ConcurrentScoreMap usage wherever possible git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7586 6c8d7289-2bf4-0310-a012-ef5d649a1542
