00027  *   Revision 1.1  2009/03/27 06:16:58  guettler
00028  *   support for gcc 4.3 compatibility (has to be checked), StatisticTools moves from utils to statistictools
00029  *
00030  *   Revision 1.7  2008/04/24 11:57:00  der
00031  *   added new measure types
00032  *
00033  *   Revision 1.6  2008/03/12 10:57:07  der
00034  *   added moving average MOVAVG
00035  *
00036  *   Revision 1.5  2008/01/17 09:59:27  der
00037  *   complexmeasure: preparations made for predictive information,
00038  *   fixed a minor bug
00039  *   statisticmeasure, statistictools: added support for adding
00040  *   std::list<AbstractMeasure*> to StatisticTools, some minor
00041  *   improvements
00042  *
00043  *   Revision 1.4  2007/12/06 10:18:10  der
00044  *   AbstractMeasure is now a abstract type for Measures,
00045  *   StatisticTools now supports AbstractMeasures,
00046  *   StatisticalMeasure, ComplexMeasure  now derived from
00047  *   AbstractMeasure,
00048  *   ComplexMeasure provides support for calculation e.g. entropy,
00049  *   uses Discretisizer,
00050  *   Discretisizer is a stand-alone class for support of discretisizing values
00051  *   TrackableMeasure derived from ComplexMeasure and provides support for calculating complex measures for Trackable objects
00052  *
00053  *   Revision 1.3  2007/09/28 08:48:21  robot3
00054  *   corrected some minor bugs, files are still in develop status
00055  *
00056  *   Revision 1.2  2007/09/27 10:49:39  robot3
00057  *   removed some minor bugs,
00058  *   added CONVergence test
00059  *   changed little things for support of the new WSM
00060  *
00061  *   Revision 1.1  2007/05/07 21:01:31  robot3
00062  *   statistictools is a class for easy visualization of measurements of observed values
00063  *   it is possible to add the observed value itself with mode ID
00064  *
00065  *                                                                         *
