Create between {@link module:splat-ecs/lib/particles.Config#qtyMin qtyMin} and {@link module:splat-ecs/lib/particles.Config#qtyMax qtyMax} particles, and randomize their properties according to <code>config</code>.
@param {object} game The <code>game</code> object that you get in systems and scripts.
@param {module:splat-ecs/lib/particles.Config} config The settings to use to create the particles.
