      The <i>Gauss-Hermite quadrature rule</i> is used as follows:
      <pre>
        c * Integral ( -oo < x < +oo ) f(x) exp ( - b * ( x - a )^2 ) dx
      </pre>
      is to be approximated by
      <pre>
        Sum ( 1 &lt;= i &lt;= order ) w(i) * f(x(i))
      </pre>
      Generally, a Gauss-Hermite quadrature rule of <i>n</i> points will
      produce the exact integral when f(x) is a polynomial of degree
      <i>2n-1</i> or less.
