Nested Adam Instance - is a usual Adam Instance, but it runs inside already created other one Adam Instance.
You can add Adam Instance as nested with "adam_instance:add(adam_instance)". As usual Adam Instance, you have to run in manually with adam_instance:start()
Nested Adam Instance will run until parent Adam Instance is running. You have to don't declare ':update', ':on_input' and ':final' functions. It forwarded by default to all nested instances.
Nested update and on_input functions runs after the parent functions call. The final functions runs before parent final function. You can stop Nested FSM with :pause or manual call :final function.
Messages and events is not forwarded to Nested FSM by default. You should do it manually with list of allowed events
You can setup forwarded events with adam:forward_events(nested_fsm, events, is_consume). Events can be string or array of strings. If is_consume is true and some event should be forwarded, it will be not pass to other nested FSM and parent FSM
