Ed's submission of the logistic regression distribution caused problems
for me because, like Ed, I have changes to the <ext/random> header in my

This first one is a new distribution. It generates coordinates for
random points on a unit sphere in arbitrarily many dimensions. This
distribution by itself is useful but if I get some other code fully
implemented it will also form the basis for yet another, more
sophisticated distribution.
Hello,
I have 2 questions :
* can't we end up dividing by 0 if all values of the normal distribution
happen to be 0?
* should the implementation be specialized for small dimensions to avoid
the normal distributions and instead generate points in a square/cube
until they fall in the disk/ball?
