@igv4321 : Have these changes documented/presented somewhere? Where should effedcts show up?

[igv4321]

The changes are trivial -- mostly maintenance, so there is no detailed documentation. They affect my packages related to FFTJet jet corrections, mainly JetMETCorrections/FFTJetObjects and JetMETCorrections/FFTJetModules. As far as I can see, everything works just fine.

[vadler]

I see. So, you expect output to be the same as before, and it indeed is?

[igv4321]

Yes, the code works the same as before. Interpolation tables do not generate output directly -- they are just used to store lookup tables of correction factors.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_1_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?
