title: How can I increase the number of subdivisions for functions in `scipy.integrate.dblquad`?
body: <p>I'm using <code>scipy.integrate.dblquad</code>, and I get this error:</p>
  
  <pre><code>UserWarning: The maximum number of subdivisions (50) has been achieved.
  If increasing the limit yields no improvement ...
  </code></pre>
  
  <p>I want to increase this limit to see if the integral is well-converged. The <a href="http://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.quad.html#scipy.integrate.quad" rel="noreferrer">documentation</a> specifies how to do this for <code>scipy.integrate.quad</code> (that function takes the maximum number of iterations as an argument), but not for <a href="http://docs.scipy.org/doc/scipy/reference/generated/scipy.integrate.dblquad.html" rel="noreferrer"><code>scipy.integrate.dblquad</code></a>.  How can I increase the number of subdivisions for <code>dblquad</code>?</p>
