+       Reworked the LUT version of the Hough Transform. This should be the default transformer now, it is 3 times faster than the normal transformer. It produces almost the same peaks, in a central event, a few differ. The reason seems to be due to rounding. The efficiency of the deconvoluter is verified to be the same, too.

+       Added ostream& <<operator for debugging purposes, because of that changed most get member function  to const.

+       Changes to compile for MACOSX at core Makefiles. Check for
+       $(ARCH) and -D$(ARCH). In order to solve cyclic dependencies
+       for libs (which is _very_ bad, but the Linux linker is friendly)
+       a few changes have to be done (moving files around) which
+       we dont do at the moment. SO: Linux users should see _NO_
+       difference!!!
