Please change name, this conflicts with DQMOffline/EGamma/plugins/ElectronAnalyzer.cc 

The plugin 'ElectronAnalyzer' should have been loaded from
 '/build/speer/cmssw/5.3/CMSSW_5_3_X_2013-08-29-0200-639/lib/slc5_amd64_gcc462/pluginEgammaEGammaAnalysisToolsTest.so'
 but instead it was already loaded from
 '/afs/cern.ch/cms/sw/ReleaseCandidates/vol1/slc5_amd64_gcc462/cms/cmssw/CMSSW_5_3_X_2013-08-29-0200/lib/slc5_amd64_gcc462/pluginDQMOfflineEGammaPlugins.so'
 because some other plugin was loaded from the latter loadables.
To work around the problem the plugin 'ElectronAnalyzer' should only be defined in one of these loadables.
