Gets the rotation axis and angle for a given
quaternion. If a quaternion is created with
setAxisAngle, this method will return the same
values as providied in the original parameter list
OR functionally equivalent values.
Example: The quaternion formed by axis [0, 0, 1] and
angle -90 is the same as the quaternion formed by
[0, 0, 1] and 270. This method favors the latter.
