/** An emitter class that holds three objects to control the creation of particles.
These objects are a <I>counter</I>, a <I>placer</I> and a <I>shooter</I>.
The counter controls the number of particles to be emitted at each frame;
the placer must initialize the particle's position vector, while the shooter initializes
its velocity vector.
You can use the predefined counter/placer/shooter classes, or you can create your own.
