#   This script was designed to act as a parent class for all scenes. It
#   provides 2 major purposes :
#
#    1) Give the Main Processing Method a Common Structure
#    2) Automatically Update & Dispose All Spritesets, Sprites, Windows or
#       any other instance variable that responds to :update or :dispose
#
#   This is a script for developers, not non-scripters. If you do not
#   plan to create scenes in RMXP, this isn't needed.
