Images from the lesson1 now acquired a "motor" which makes random motion. They yet do not know about each
		other, this may be done at the next step when they courteously yield the pleace to a peer.

		The job took a bit more than expected because of spatial part and refactoring of the project.

		The function name "image" is replaced with "buddie" because it feels like closuers produced by the program 
		do behave more like live entitities.
