Description
For many applications I'm using Euler angles rather than Quaternions (where they need to be sensibly user-edited).
Currently we have an ofVec3f ofQuaternion::getEuler() but no ofQuaternion::setEuler(const ofVec3f &).
And I can't seem to find a function on the internet which inverts our getEuler() (suggesting that our getEuler might also be broken).

Research direction
Start by locating ofQuaternion::getEuler() and the ofQuaternion declarations and implementations. Check the existing Euler-angle conventions and whether getEuler() round-trips correctly before designing setEuler(const ofVec3f&). Done means providing the setter and resolving or documenting the suspected getEuler inversion issue with appropriate verification.
