 The algorithm is the descending Landen transformation, which is explained in detail in L. Howell's MIT PhD thesis. Additional transformations where used from Gradshteyn & Ryzhik "Table of Integrals, Series, and Products", Fifth Edition, and M. Abramowitz and I.A. Stegun, "Handbook of Mathematical Functions," Dover, 1965.
 
 This algorithm was originally implemented in MATLAB by Toby Driscoll.
