Title: normrandvel

added a filter that randomizes velocity according to a normal distribution. This is more computationally intensive than randomvelocity, but should yield more natural results. The normal approximation is accomplished through a modified Marsaglia polar method, with a bound on the number of redraws allowed. There is approximately a %25 redraw rate, but it is limited to 3 tries per outcome. In event of failure the velocity is left unchanged.
