This plugin does not do much on its own, it lets other plugins register additional content to compute on the fly when asked, e.g. the Wikipedia plugin can store the Web page of the definition they just gave so users wanting to know more about a definition can use the "plus" function to get the URL to the Web page. There can be only one handle registered at one time by target (so by channel, user, etc). External plugins use the `add_handler` to set the current handler for a target.
