--What it does:
--[1]: Registers callback when you open the file and move the time slider.
--[2]: UnRegisters when you open a different max file.
--
--How to use:
--[1]: Put code into a script controller of a dummy object.
--[2]: Make sure last line of script controller is:
--   : [0,0,0], or other valid point3 if position script.
--   : quat 0 0 0 1, or other quaternion if rotation script.
--   : ect...
--[3]: If you want, you can also edit this code to handle
--     "when constructs" and "change handlers".
--
--My personal application:
--[1]: Use to force update script controllers that are not
--     Executing in the correct order.
