This is a barebones version of a display of the Julia set.  It
has deliberately been left simple and free of options so that the
basic idea is clear and so that it can be used as the basis of
more capable versions.

This program is based on material given in "Chaos, Fractals,
and Dynamics", Robert L. Devaney, Addison-Wesley, 1990.

The point in the complex plane for which the Julia set is computed
is given on the command line, as in

     julia1 .360284 .100376

which displays the Julia set for the complex number .360284 + .100376i.
