Orbit controls revisions

[dylanebert]

• Naming, formatting for consistency
• Removed setPosition, since I believe it has the same function as setting camera.position = directly, which OrbitControls now listens for. Let me know if I'm mistaken and there is a different intended functionality
• Update the camera-updates example to test the new method

Thank you, I didn't notice you had updated it to listen to the camera's position.

Aslo, It appears that there is an error in the revised version of the function.

The corrected version should be:

desiredRadius = Math.sqrt(dx * dx + dy * dy + dz * dz);
desiredBeta = Math.atan2(dy, Math.sqrt(dx * dx + dz * dz));
desiredAlpha = -Math.atan2(dx, dz);

(desiredRadius and desiredAlpha should be swapped)

Thank you.
