@davidlange6 we need this change to allow introduction of the ElectronStream for the 50ns HLT menu. Can we move forward with the tests?

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs once checked with relvals in the development release cycle of CMSSW (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
