Rename summary to network_summary where appropriate
Use station numbers for column names

Pass a SAPPHiRE cluster object to CoincidencesESD to give it the
station numbers
The cluster is very limited, it does not contain correct positions, nor
any detectors.
Improved pulseheight histograms

Extended the max pulseheight range for histograms to 2500 mV
This should fit all possible pulseheights: 4096 * .57 = 2335 mV
The bin size is still the same (10 mV)
Also increased the range for the plot in the flot settings.
To ensure the same plot range for all histograms.
Slightly thinner plot lines
