Fast ND multidimensional gaussian mixture random generator

After fixing a small bug in the code, I found this program works well to generate multidimensional mixture-gaussian distribution.

comment: A super clear paper on Particle Simulations. After you read this paper, you can clearly see that KDE is actually a special case of this algorithm.
