Previouly derived aforementioned angles correctly seemed inaccurate and somewhat unusable (given their output was in radians). This update uses the a person's mesh positions, and chooses specific points for accurate results. It also adds directionality of the movements (_e.g. pitching head backwards is a negative result, as is rolling head to the left).
The webcam.js file has also been updated to showcase the correct output in degrees (reducing potential user confusion)
