…the clustering algorithms + modification to the dataformat to include a collection of clusters in the multicluster + some minor modification to the parameters python and HGCClusterAlgo.cc class

Clustering infrastructure

…clustering and multiclutering next commit will use references

…e collection references instead of unique_ptr to collections + add of parameter for geometrical cluster 2D in hgcalTriggerPrimitiveDigiProducer_cfi.py

…) member functions as const in HGCalCluster class

…in IC code just to debug the C2d (need the sum of the energy)

+ modifications to the cluster classes and their implementation:
parsing of the eventSetup and Event in the clusterise functions
(needed to retrieve GlobalPointers to the cartesian position of the 2D) + creation of a *temporary-C3d* used to test the C2d + global cleaning

…turns the calibrated pT in mip units

…vector<HGCalTriggerCell*> and std::vector<Cluster*> have been implemented + removal of Event and EventSetup from the clustering functions parameters, using the GlobalPointer from TC

…lasses to the respective Impl.

2) Modification of the classes_def.xml and classes.h
3) Restored the the type of centre and centreProj (previously centreNorm) as GlobalPoint
4) other minor changes + few variable renames + overall cleaning

…dles in input to the clusterization functions have been replaced by PtrVectors
