0011  Description: An auxiliary class of the Particle-Flow algorithm,
0012               for the Estimation of the Energy Resolution in ECAL and HCAL;
0013               the Resolution can be parametrized either as function of raw or as function of calibrated Energy Deposits;
0014               currently, it is parametrized as function of **calibrated** Energy Deposits
0015 
0016  Implementation:
0017      Original Implementation of Resolution functions in PFAlgo/PFBlock by Colin Bernet;
0018      Code moved into separate Class by Christian Veelken
