| :: Double | precision (e.g. 1E-9)
| | -> Double -> Double | function to be integrated on the interval (a,b)
| | -> Double | a
| | -> Double | b
| | -> (Double, Double) | result of the integration and error
| Numerical integration using gsl_integration_qng (useful for fast integration of smooth functions). For example:
> let quad = integrateQNG 1E-6
> quad (\x -> 4/(1+x*x)) 0 1

| | -> Double -> Double | function to be integrated on the interval (a,b)
| | -> Double | a
| | -> Double | b
| | -> (Double, Double) | result of the integration and error
| Numerical integration using gsl_integration_qags (adaptive integration with singularities). For example:
> let quad = integrateQAGS 1E-9 1000
> let f a x = x**(-0.5) * log (a*x)
> quad (f 1) 0 1
