Additional Notes
- restore - Table representing internal restore functions. You should use the restore table that is passed by the engine to your hooked restore function.
- This function will read and subsequently return a variable of any type (including tables and vectors). If you're unsure of what the return type is, you can use the type function to discover it (see the second example)
