Initial Velocities

The velocities are initialized to random directions with magnitudes that give a mean velocity which corresponds to the applied temperature. The random magnitudes are sampled from a Gaussian distribution to simulate what the distribution of velocities naturally looks like. Note, that this is not very important since the velocities will assume a Gaussian shape as the simulation progresses regardless of the initial velocities.
