/**
* This is the starter function of game loop..
* It simply checks the event pool to get any keyboard or
* mouse events that occured.
* It controls both of the event listeners to call their
* listener functions
* This function has its time counter and its run time can be
* get via getEventTime function.
* TODO collecting the currently pressed and not released keys and defining new events for them
* may be useful.. ex: for ctrl+a or alt+e or something.. However current keyboardEvent probably
* will need to be changed..(maybe adding a get super key and get key functions? )
