RANDOM // 
FUNCTION: random( dims, mu, sigma[, rand] )
Creates a multidimensional array of normally distributed random numbers.

@param {Number[]} dims - dimensions
@param {Number} mu - mean parameter
@param {Number} sigma - standard deviation
@param {Function} [rand=Math.random] - random number generator
@returns {Array} multidimensional array filled with normal random numbers
