*   $Log: trackablemeasure.h,v $
*   Revision 1.1  2007/12/06 10:18:10  der
*   AbstractMeasure is now a abstract type for Measures,
*   StatisticTools now supports AbstractMeasures,
*   StatisticalMeasure, ComplexMeasure  now derived from
*   AbstractMeasure,
*   ComplexMeasure provides support for calculation e.g. entropy,
*   uses Discretisizer,
*   Discretisizer is a stand-alone class for support of discretisizing values
*   TrackableMeasure derived from ComplexMeasure and provides support for calculating complex measures for Trackable objects
*
*   Revision 1.3  2007/09/28 08:48:21  robot3
*   corrected some minor bugs, files are still in develop status
*
*   Revision 1.2  2007/09/27 10:49:39  robot3
*   removed some minor bugs,
*   added CONVergence test
*   changed little things for support of the new WSM
*
*   Revision 1.1  2007/05/07 21:01:31  robot3
*   statistictools is a class for easy visualization of measurements of observed values
*   it is possible to add the observed value itself with mode ID
*
*                                                                         *
