cleanup in heppycore test cfgs
removed java style, clean up, unittests in cmsswRelease
removed again the custom init scripts

these scripts where resulting in everything being imported all the time,
e.g.
from PhysicsTools.Heppy.analyzers.examples.SimpleJetAnalyzer import SimpleJetAnalyzer
would result in having all modules in Heppy + lots of useless root stuff imported,
hence a very slow import.
bug fix after clean up in cmsswRelease
simple_example_2 working on standard mini aod relvals
simple_example_2 working with Z->mumu events
clean up of imports in example_autofill.
