## Detailed Description

Probability density function and -log(p) of von Mises distribution

$f(x|\mu,\kappa) = \frac{\exp \left(\kappa \cos (x-\mu)\right)}{2\pi I_0(\kappa)}$

This is the proper treatment for a "normally distributed" angle. When $$\kappa$$ becomes infinite, the distribution tends to a gaussian, and $$\kappa = 1/\sigma^2$$.
