I started cleaning up the code.

I have to add back:
	1. examples of usage of objecTracking library
	2. programes to check that objectTracking works as it should i.e. usefull debuging programs when objectTracking is not working as intended
Merge branch 'master' of https://github.com/Chobotnatec/Drifter

Conflicts:
	objectTracking/examples/preprocessImage.cpp
