commit d6439bd96cf670d4b164cb78dff2358293539c83 Author: Raymond Toy toy.raymond@gmail.com Date: Mon Mar 14 08:43:05 2011 -0400

Fix typo; update required accuracy.

o The names of the elliptic functions changed and we forgot to update the tests to use the new names. o Reduce required accuracy of some tests.
