added configurable parameters maxAssocCaloE and maxAssocCaloEDeltaRSize

These configurable parameters calculate the associated calorimeter energy associated with a track (i.e. the sum of all calo tower deposits within a cone around the track)
Good point, all other cases of local copies should be replaced with using c references

```
const reco::TrackCollection& trackCollection
```

```
const edm::ValueMap<reco::DeDxData>& dEdxTrack
```
