    [values,longs,lats]=m_elev(varargin);

## Help text

     M_ELEV Contour elevation onto a map using a 1-degree database
            M_ELEV contours elevations at 1000m intervals for the map.
            M_ELEV(OPTN (,LEVELS) (,ARGS,...) ) lets you change various options.
            if OPTN=='contour', contour lines are drawn. for OPTN=='contourf',
            filled contours are drawn. LEVELS are the levels used, and ARGS
            are optional patch arguments of line types, colors, etc.

            [CS,H]=M_ELEV(...) allows access to the return arguments of the
            contour/contourf call.

            [ELEV,LONG,LAT]=M_ELEV([LONG_MIN LONG_MAX LAT_MIN LAT_MAX])
            extracts elevation data for the given lat/long limits (without plotting).
