adding electron shower parametrization hists
See Rec!2319 for algorithm description and more details.
Sigmoid parameters are based on ideal shower shape MC (see Rec!2319).
DLL is based on Bd2Kstee upgrade sample with long tracks in Ecal acceptance with p>3 GeV/c and either electron (defining signal; not coming from charged pion or kaon decays) or charged pions or kaons (defining background).

Originally added to SIMCOND, see SIMCOND!152. Requested to move to ParamFiles, in part to avoid implementation issues in Moore (testing), in part to move PID parametrization outside of conditions database.
