#handle_options(given_options, default_options, other_allowed_keys = []) ⇒ Object

takes given options and default options, and optionally a list of additional allowed keys not specified in default options (this is useful when you want to pass options along to another function but don’t want to specify a default that will clobber that function’s default) raises ArgumentError if the given options have an invalid key (defined as one not specified in default options or other_allowed_keys), and sets default values in given options where nothing is set.
