 Methods for Integrating Functions given fixed samples.

   trapezoid            -- Use trapezoidal rule to compute integral.
   cumulative_trapezoid -- Use trapezoidal rule to cumulatively compute integral.
   simpson              -- Use Simpson's rule to compute integral from samples.
   romb                 -- Use Romberg Integration to compute integral from
                        -- (2**k + 1) evenly-spaced samples.

   See the special module's orthogonal polynomials (special) for Gaussian
      quadrature roots and weights for other weighting factors and regions.
