/** @short  implements flat/deep detection of file/stream formats and provides
            further read/write access to the global office type configuration.

    @descr  Using of this class makes it possible to get information about the
            format type of a given URL or stream. The returned internal type name
            can be used to get more informations about this format. Further this
            class provides full access to the configuration data and following
            implementations will support some special query modes.
