New calo reconstruction algorithm

Nuria Valls Canudas requested to merge nuvallsc_caloGraphClustering into master

This is a draft proposal for an alternative calorimeter cluster reconstruction algorithm based on graphs. Some documentation about the algorithm and preliminar results can be found on the atached PDF.

graph_clustering.pdf (updated)

By now, it has shown to be slightly better than master in terms of efficiency and faster in execution time for events with more than 1k hits/event.

In Moore!1217 (merged) there is a modification to run this algorithm instead of FutureCellularAutomataAlg and CaloFutureShowerOverlap in the standalone_hlt2_calo_efficiency configuration (for example).

In the following slides there is an update of the metrics after the modifications proposed:

This is ready for testing.
