Camilo's Kaluza Klein taus MC

This is Camilo's KK taus configuration file for MC production (done by him at the UniAndes Tier-3): kktaugen.py.txt

The event generator used was Comphep as it can be seen in the following fragment. Pythia was used for the hadronization with the following driving parameters:
