2: x(10), y(0) : Catch exception DIVIDE_EXCP, prints error and quit

This code demonstrates a way to broadcast messages to many listeners. I'm scrapping this code I worked on for few hours. Why? Because for now I'm going forward with one global event dispatcher. Right now on iDevices it doesn't makes any sense to buffer the events, as the OS already buffers them. Maybe someday I'll return to something similar.
