/**
 * A CollisionArena is defined as an arena in which collisions
 * may take place.<p>
 *
 * CollisionArenas must be able to report their size and 
 * insets, and return a Vector of the Sprites contained in the 
 * arena.<p>
 *
 * CollisionArenas must also implement two methods for handling
 * sprite and edge collisions, respectively.
