Implemented plotting of eta of BTI triggers from CMSPosition of DTBtiTrigger Data
Implemented helper function, that plots divided canvases with a given input vector
of TH1D*.
Implemented plotting of BX Id distribution for BTI events and plotting of
the distribution in sector and wheel of BTI trigger events with no Theta events
Added own plotting style class
Introduced new Analyser class structure, beginning with BTI analysis.

This is done to make the code in the main function clearer and to make the analysis of the given input samples
easier with multiple conditions.

Each analysis now should work by calling a wrapper class for each input file.
The Wrapper then calls the analysis classes for each subsystem. The plots can
be stored via calling savePlots on the wrapper.

The histograms, especially 2D, have to be made "colz"-Plots again.
Added the missing module for the GenParticle muon filter already referenced by the python file
for the DataAggregator
Added first classes for TracoAnalyser which are not yet used.

New Plot: Number of BTI Events without theta hit averaged over the whole wheel
Added GenParticle analyser classes.
