Class Description

 TConfidenceLevel

 Class to compute 95% CL limits

 Default constructor

 a constructor that fix some conventions:
 mc is the number of Monte Carlo experiments
 while onesided specifies if the intervals are one-sided or not.

 The destructor

 Get the expected statistic value in the background only hypothesis

 Get the expected statistic value in the signal plus background hypothesis

 Get the Confidence Level for the background only

 Get the Confidence Level for the signal plus background hypothesis

 Get the Confidence Level defined by CLs = CLsb/CLb.
 This quantity is stable w.r.t. background fluctuations.

 Get the expected Confidence Level for the signal plus background hypothesis
 if there is only background.

 Get the expected Confidence Level for the background only
 if there is signal and background.

 Get the expected Confidence Level for the background only
 if there is only background.

 Display sort of a "canonical" -2lnQ plot.
 This results in a plot with 2 elements:
 - The histogram of -2lnQ for background hypothesis (full)
 - The histogram of -2lnQ for signal and background hypothesis (dashed)
 The 2 histograms are respectively named b_hist and sb_hist.
