Point to the landing page of the celestial mechanics example.
The Runge Kutta stuff belongs in its own directory.
Better name.
Separate the integrating from the display.
Capture the relative error transformation as a transformation of the
time series, not just the mapping function; show the example more
explicitly.
Separate the example integrations out into their own DVL file, so that
the integrator can be included safely from elsewhere (notably
celestial.dvl).
Consistent interface: the 1d estimate is the cadr of the state.
Right.  Now I remember why I needed an explicit "plot estimate" --
because the results come back as a list of lists, and gnuplot-alist
wants an alist.
Explain and comment examples.
Drop in gnuplot to make this standalone.

Also rearrange and better explain the examples.
Simplify the instructions by implementing part of them.
Better names.
