        /RAMP Up tRamp

        /RAMP Up must be used for Lissajous subscans.

        At the start of a Lissajous subscan, paKo will insert a "ramp" along a
        straight line, i.e., a linear OTF segment, increasing the count of
        segments by 2.  This ramp up starts with speed 0 relative to the
        source and joins smoothly with the start position and velocity of the
        Lissajous segment.  The purpose is to avoid a sudden aceleration at
        the start of the Lissajous segment.  Command DIY lists this inserted
        OTF segment as well as the Lisssajous segment.  The inserted ramp up
        segment and the Lissajous segment become part of the same subscan.

        Example:

        SUBSCAN 100 200 0.01 0.02 -10 -20 0.1 0.2 /ramp up 9

        Lissajous subscan with a ramp up of at least 9 [sec].
