Applying the inverse transform method to the normal distribution entails evaluation of the inverse normal. This is the Beasley-Springer-Moro algorithm for approximating the inverse normal.

Input: u, a sacalar or matrix with elements between 0 and 1
Output: x, an approximation for the inverse normal at u

Thanks to Ben Petschel who provided optimized code that brings it almost on par with the builtin (compiled) norminv/erfcinv!
