| Utility: The Photon class
|
|   This is an unbelieveably trival class used to represent a photon in
|   the Compton experiment monte-carlo programme used as a consolidation
|   excercise
|
|   It is so trivial I havnt even written a .cpp file and ive also 
|   putmin some of the const qualifiers.
