Rotation class with the (3D) rotation represented by angles describing first a rotation of an angle phi (yaw) about the Z axis, followed by a rotation of an angle theta (pitch) about the new Y' axis, followed by a third rotation of an angle psi (roll) about the final X'' axis.

This is sometimes referred to as the Euler 321 sequence. It has not to be confused with the typical Goldstein definition of the Euler Angles (Z-X-Z or 313 sequence) which is used by the ROOT::Math::EulerAngles class.
