Various improvements

Following up on list of suggestions in #59.

A few specific notes:

• verbosity levels are: 0 = no printouts, 1 = warnings only, 2 = warnings & info, 3 = warnings, info, debug
  (2 is the default)
• using print() as a function instead of a statement will help with eventual python3 transition
• also ported the separate subjetBTagDiscriminator list from Adding some tools and fixing bugs for next version #47

DeepFlavour support still needs to be added, but I'm not sure what that entails.

Hi @kpedro88 sorry for the late reply about this, but I am a bit confused with the associatedTask option. If this is false, then I would need to include a process.endpath = cms.EndPath() in my other python cfg file or what exactly I need to include? Thanks!

@alefisico with associateTask=False, you need to associate the jetTask to a cms.Path() or cms.EndPath().

In TreeMaker, I do the following (to avoid worrying about jetTask separately from my other producers):

ok that was my confusion, you do not only need to associate the jetTask to cms.Path() but also include the module which uses the output collections of the JetToolbox to the path, like in your line 912.
I got a question about this and it took me a while to understand this.
Thanks, I think I need to add this information in the twiki.
