on par with michal's latest recipe. needs modifications to match my previous setup
added collections to the event content, fixed crab cfg files
HLT Tau collection made configurable
bug fix
added pre-filtering tracks. Lopper now can be stopped with crtl-C without destroying the universe
bypass the offline-online matching. In this way you can keep on developing the code, but forget about any real physics
code is more general, you can pass different HLT taus collections and run once
