`RectBivariateSpline.``integral`(xa, xb, ya, yb)

  Evaluate the integral of the spline over area [xa,xb] x [ya,yb].

  Parameters: | xa, xb : float The end-points of the x integration interval. ya, yb : float The end-points of the y integration interval.
  Returns: | integ : float The value of the resulting integral.
