LA tree production

Pixel tree production

Setup procedure is explained here
https://github.com/BenjaminMesic/PixelTree-ProductionTool
(instructions.txt is deprecated so ignore it please)

After you finish setup, open TreeProduction.py and set these four lines
https://github.com/BenjaminMesic/PixelTree-ProductionTool/blob/master/TreeProduction.py#L16-L19
(CMSSW is not mandatory but is ok for bookkeeping.)

After you did all that just run the script. It will create bunch of scripts (in batch folder) ready to be sent on batch.
Before sending you can just open one python script and see if everything is done correctly. You
can even change number of events to e.g. 5 and run script interactively.

How does script actually creates jobs? 
There is the template script which is used for making jobs.
https://github.com/BenjaminMesic/PixelTree-ProductionTool/blob/master/templates/pixel.py
(Note that there are many different templates but only one which is called pixel.py is actually used,
other templates are used for different configurations, i.e. cosmics, VCAL, etc... Most recent are
ones which have phase1 in its name. If you want to use other template, it must be called pixel.py)

If you are going to send jobs, they will be automatically stored on EOS
https://github.com/BenjaminMesic/PixelTree-ProductionTool/blob/master/TreeProduction.py#L33
I don't know if you have permissions to store there. Anyway, you need to manually create directory
(from line 33) on EOS. In case you wish to make files on EOS, please fill the google doc what you did so
that I can follow what is going on.

Right now, sending jobs is not configurable as a variable so you need to (un)comment 
https://github.com/BenjaminMesic/PixelTree-ProductionTool/blob/master/TreeProduction.py#L235
in order to send jobs.
