A @GOptionGroup@ struct defines the options in a single
group. The struct has only private fields and should not be directly accessed.

All options in a group share the same translation function. Libraries which
need to parse commandline options are expected to provide a function for
getting a @GOptionGroup@ holding their options, which
the application can then add to its 'GI.GLib.Structs.OptionContext.OptionContext'.
