added default ctors to embedded classes to avoid unit test crashing

[apfeiffer1]

for some reason unknown to me, the serialisation unit test of this package crashes in the 74x-ROOT6 IB (though not in the regular IB).

This PR fixes the crash by adding default ctors to the embedded classes in the CaloParams class which initialise the members.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_X IBs unless changes (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @nclopezo, @ktf, @smuzaffar

Sounds like this fixes for ROOT6 which is still 7_4_X.

Yes, but a PR for this was just merged into 7_4_X. That will take care of ROOT6.
