    //  Here we'll create a basic repeating event.

    //  The way a repeating event works is that it is placed into the queue once, 
    //  and when it runs its 'repeatCounter' is reduced by 1 and it's moved back into the queue again.
    //  To this end the queue will only ever have 1 event actually in it.

    //  The first parameter is how long to wait before the event fires. In this case 2 seconds (you could pass in 2000 as the value as well.)
    //  The second parameter is how many times the event will run in total. Here we'll run it 10 times.
    //  The next two parameters are the function to call ('createBall') and the context under which that will happen.

    //  Once the event has been called 10 times it will never be called again.
