Rodrigues' axis-angle rotation

The script shows how to rotate vectors in space about an axis through the origin as well as any arbitrary axis

Includes 2 code blocks. The first one uses the Rodrigues' formula to rotate a vector in space around an axis. The second block can be used to perform rotations about an arbitrary axis
1) Rotates a vector in 3D space about an axis passing through the origin
2) Rotates a vector in 3D space about an arbitrary axis
Can be used for generating cones in space since in the stated example the axis of rotation and the rotation vector have a common origin
