It was insipred by godot 4's ProcessGroup system, however while Godot 4's implementation tries to hide threaded processing as much as possible, this implementation focuses on making it explicitly known and obvious to the user, in a (hopefully) almost bolierplate free way. Also with the available options this node can be used for other purposes, like multi threaded cron job like method calls when paired with a Timer in manual mode.
