Recipe to run HtoWWElectrons reconstruction

Hi all,

this is a recipe to get the reconstruction from digis to a ROOT tree with high-level quantities:

1) create the working area
> scramv1 project CMSSW CMSSW_1_3_1

2) setup environment
> cd CMSSW_1_3_1/src/
> eval `scramv1 ru -csh`
> project CMSSW

3) checkout some cfg to patch
> cvs co RecoMET/METProducers/test/CaloCandidatesFromDigis.cfi
> cvs co Configuration/StandardSequences/data/Reconstruction.cff
> cp ~emanuele/public/patches/1_3_1/CaloCandidatesFromDigis.cfi RecoMET/METProducers/test/CaloCandidatesFromDigis.cfi
> cp ~emanuele/public/patches/1_3_1/Reconstruction.cff Configuration/StandardSequences/data/Reconstruction.cff

4) setup CVSROOT to Pietro repository and checkout the package:
> source ~emanuele/public/cvs_setup_htoww.csh
> cvs co HtoWWElectrons

6) build cmsRun
scramv1 b

7) run it:
> cmsRun HtoWWElectrons/HtoWWTreeDumper/test/hToWWAnalysis.cfg

this will produce the tree "default.root" in the current dir (and also some monitoring ROOT files with histograms)

8) If you want to do an extensive production use "run.pl" tool:
