Sapp/Phasor Compatibility Failure - useful but broken

-- ============ THIS WAS AN ATTEMPT THAT FAILED - SCRIPT DOES NOT WORK - BUT CONTAINS VALUABLE SCRIPTING ELEMENTS =============

-- Sapp and Phasor Compatibility Module
-- Created by Wizard
-- Add this line to the end of your script to use this module:
-- _G = require"thefilenameofthisscript"

--[[
How to install this module:
Download the script, find your server directory, and put it in the lua folder. If your server does not have a 'lua' folder,
then just create it manually.

How to use:
Using this script is easy, simply add this line to the BOTTOM of your script:
_G = require"thefilenameofthisscript"  -- whatever you name this script, should refer to this file name.
