<code>romberg</code>,
to compute multidimensional integrals.
However, the error calculations do not take the errors of nested integrations
into account, so errors may be underestimated.
Also, methods devised especially for multidimensional problems may yield
the same accuracy with fewer function evaluations.

<p><code>load(romberg)</code> loads this function.
