public interface Cluster

To make analysis easier it would seem a good idea to make the cluster description independant of the underlying calorimeter, i.e. use theta, phi and radius rather than calorimeter specific quntities such as layer number. But is this really practical? Are theta, phi and radius the right quantities, including for endcap clusters? When clusters are "refined" will Calorimeter Hits be shared? If so does Cluster need to take this into account? Should clusters implement 3-vector so they can easily be used with Garys eventshape and jet finding routines? What else do we need?
