// This is how to store a class inside a TClonesArray, useful for
// e.g. tracks or in general anything where you have many objects per event.
// This class doesn't play the virtual base class inheritance game we do
// for our dst's, so old files won't be readable if you change this class
// root might still be able to read parts of old files but I really 
// wouldn't rely on this
