version = 0.2



--Notes from chummy:
  --[[ -----------------------------------------------------------

    If you are editing variables in the global scope
    (Variables which are not local inside of your function,
    or above it), use _G.  It means GLOBAL.

    If you wanted to make it so component/sides/chestAccess/transposer
    are local, you can make this function return them, like so:

    --return component, sides, chestAccess, transposer

    Note that you would have to remove _G from the declarations.

    I suggest searching "Variable Scoping In LUA"
