    BillboardRotationCalculator is used to calculate the quaternion to rotate an object by to align with a new vector along an axis. More specifically, this calculator is used along a SceneObject's local X/Z-axes and global Y-axis. These calculators only take in vec3's as SceneObject manipulation is handled in BillboardController.
