This pull request is fully signed and it will be integrated in one of the next CMSSW_7_0_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

[vadler]

@davidlange6 : Could this please be merged as soon as possible, since #3667 is waiting for it to be updated accordingly?

[vadler]

Thanx, @davidlange6 :-)
