Generates a random number drawn from a normal (Gaussian) distribution with a given mean and standard deviation, using the Box-Muller algorithm. A new random number is generated every time the formula is evaluated.

To draw a number from the "standard" normal distribution, use the values of 0 for mean and 1 for stdDev.
