* Fix script error in old state machine example * Add a module with a more complex state machine, that can be created and controlled through the Lua API. Useful for interactive installations * Add an example asset for the new state machine and rename the old linear "state machine" to luastatemachine Co-authored-by: Malin Ejdbo <malin.ejdbo@gmail.com>
