<p> A general recursive array writer. The last four parameters allow
a great deal of freedom in choosing the output format of the
array. The defaults for those parameters give output that is
gnuplot-readable. But using <code>(",", "{", "}", ",
")</code> would output
an array in a format that Mathematica could read. <code>item_sep</code>
should not contain <code>%</code> (or if it does, it should be escaped to
<code>%%</code>) since it is put into a format string.</p>
