local DeltaTable ={
--[[
This module is for getting the difference between a table and then
being able to merge it back in.
-- Specifically great for networking as it allows us only to send what has changed
This is an independant Module because it has enough parts to it, that it should be
seperated from ADTs and or some sort of "Table" lib. This is abstractly a table differ.
