* The ObjectTracker tracks ObjectTargets, ImageTargets, CylinderTargets
* or MultiTargets contained in a DataSet.
* The ObjectTracker class provides methods for creating, activating and
* deactivating datasets. Note that methods for activating and deactivating
* datasets should not be called while the ObjectTracker is working at the
* same time. Doing so will make these methods block and wait until the
* tracker has finished.
* The suggested way of swapping datasets is during the execution of
* UpdateCallback, which guarantees that the ObjectTracker is not working
* concurrently. Alternatively the ObjectTracker can be stopped explicitly.
* However, this is a very expensive operation.
