FourVector is a simple representation of a physics 4 vector.
For compatibility with existing code, the basic expected geometrical access methods are povided. Also, there is a templated constructor that will take another vector (HepLorentzVector, GenVector, ...) which must have the following methods: x(), y(), z(), t().

templated constructor this is used ONLY if T is not arithmetic
