- more examples cleaning (move simple examples to interm examples)
- moved the createCamera method out of Calibration to a TrackerUtil class: so all of the Utils files (Utils, GeometryUtils, VideoUtils, TrackerUtils) are now factory, no scene graph object are instantiated in the module classes (i.e. video, tracker, etc).
- Added a TrackerConfiguration (same as VideoConfiguration or any future Configuration class)
- renamed TrainingSupport to TrackerTrainingSupport as we may have other TrainingSupport in the future (e.g. Sensor, Mapper, etc)
