// Class description:
//
// This is the abstract base class for a user's parallel world.
// The user MUST NOT create the world volume, and should either get it
// from GetWorld() protected method, and set inside the Construct() method.
// The constructor must take a unique name of the parallel world, which is
// used for the name of the world physical volume of this parallel world.
