 * I tried to edit this article in a way that kept the spirit of the original material and corrected some errors, but it rapidly became redundant and awkward. Even this version is a flawed though correct.  Please feel free to restore any wording from the previous version, if you feel it is helpful. Prof McCarthy (talk) 07:17, 3 September 2011 (UTC)
