operator to Hep3Vector makes it trivial to use UnitVector as an argument to any routine that takes a Hep3Vector. There will be cases where it would be beneficial to have a special method taking advantage of the knowledge that a UnitVector need not be normalized. For the present, we will not attempt to obtain this advantage. --------------------------------------- Rotation classes inheritance structure:--------------------------------------- I am telescoping a lot of thought into a few words here. ZOOM has RotationInterface and LorentzTransformationInterface()
