Got relative angle diffsion to change cos theta to theta at the beginning to make normalization easier.
Implemented conversion of cosTheta to Theta at calculation time fully. The results don't look right though. I should see a flat distribution of angles, instead I see a flat distribution of cosTheta which looks like a mcdonalds M of angles.
Relative angle diffusion script finished. In 3D we expect a uniform cosTheta distribution for brownian dynamics because of the probability of going straight being much less than going 90 degrees.
