For #9160 d776416

Adding calculation of signed interaction point with respect to the tau direction. This PR should not alter other monitored quantities.

The code changes are satisfactory, and Jenkins tests against baseline CMSSW_7_5_X_2015-07-02-2300 show no significant differences, as expected. The error that Jenkins notes above is a failure of unit tests for #9758, the 76X version of this PR. The error doesn't seem to be related to this PR.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_5_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
