/*
 * SOURCE FILE : EnemyFactory.h
 *
 * Definition of class EnemyFactory.
 * Makes objects descended from EnemyObject.
 * It is absolutely vital that all enemies are created and deleted this way if memory leaks are to be avoided.
 * Don't forget pesky enemies like MutantObjects that only appear half way through a level. They still need
 * to be created this way.
