Method rotateAroundAxis

src/main/java/org/bukkit/util/Vector.java:502–507

Rotates the vector around a given arbitrary axis in 3 dimensional space. Rotation will follow the general Right-Hand-Rule, which means rotation will be counterclockwise when the axis is pointing towards the observer. This method will always make sure the provided axis is a unit vector, to n
