Brian, please make this for CMSSW_8_0. Also I don't think this belongs on IOPool/Common since it has nothing to do with PoolSource or PoolOutputModule. Is there a package which this code depends upon which also depends upon all the other packages it needs? If so, then this code should go into that top most package.

[Dr15Jones]

After a quick look, I take back my objection to putting this in IOPool/Common.

@Dr15Jones - will open a second PR for CMSSW_8_0_x branch. However, I suspect we'll be asked for a backport to a release so I'll leave this open.

@cmsbuild, please test

@bbockelm @Dr15Jones - being a completely new function, we can stick with 76x and rely on the forward port

The tests are being triggered in jenkins.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_6_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar
