Composed a brainstorming document for proper MVC implementation.

I proposed to move the scannerstrategies package out of the control
package. Moreover I  introduced new control classes for handling
IconSet instances and routing operations that can be applied on such.
The last paragraph deals with the inter class communication and 
especially inter package communication, to define a stricter MVC 
design.
Marked "obsolete" brainstorming documents as such.

I left them in this folder as they are intended to give others the chance
to reproduce my "chain of thoughts".
Restructured the UML diagram to display the improved MVC design.
