Detailed Description

Analyses cell properties and identifies bad cells.

This is used for bad channel identification in EMCal and DCal. The class builds a mean distribution of certain cell observables and compares single cell properties to this mean. That way bad channels (far off the mean) are identified and flagged. A .pdf file with their spectra is created. This should be cross checked by hand.
