// DESCRIPTION:
// Standard explosion object that is spawned by other entites and not map designers.
// Explosion is used by many of the weapons for the blast effect, but is also used
// by the Exploder and MultiExploder triggers. These triggers create one or more
// explosions each time they are activated.
