Function documentation

 LikelihoodIntervalPlot default constructor
 with default parameters
LikelihoodIntervalPlot(LikelihoodInterval* theInterval)
 LikelihoodIntervalPlot copy constructor
void SetLikelihoodInterval(RooStats::LikelihoodInterval* theInterval)
void SetPlotParameters(const RooArgSet* params)
void Draw(const Option_t* options = 0)
 draw the log of the profiled likelihood function in 1D with the interval or
 as a 2D plot with the contours.
 Higher dimensionals intervals cannot be drawn. One needs to call
 SetPlotParameters to project interval in 1 or 2dim

 Options for drawing 1D interals

 For 1D problem the log of the profiled likelihood function is drawn bby default in a RooPlot as a
 The plotting range (default is the full parameter range) and the precision of the RooCurve
 can be specified by using SetRange(x1,x2) and SetPrecision(eps).
 SetNPoints(npoints) can also be used  (default is npoints=100)
 Optionally the function can be drawn as a TF1 (option="tf1") obtained by sampling the given npoints
 in the given range

 Options for drawing 2D intervals

 For 2D case, a contour and optionally the profiled likelihood function is drawn by sampling npoints in
 the given range. A 2d histogram of nbinsX=nbinsY = sqrt(npoints) is used for sampling the profiled likelihood.
 The contour can be obtained by using Minuit or by the sampled histogram,
 If using Minuit, the number of points specifies the number of contour points. If using an histogram the number of
 points is approximatly the total number of bins of the histogram.
 Possible options:
  minuit/nominuit:     use minuit for computing the contour
   hist/nohist   :     sample in an histogram the profiled likelihood

 Note that one can have both a drawing of the sampled likelihood and of the contour using minuit.
 The default options is "minuit nohist"
 The sampled histogram is drawn first by default using the option "colz" and then 8 probability contours at
 these CL are drawn:  { 0.1,0.3,0.5,0.683,0.95,0.9973,0.9999366575,0.9999994267} re-drawing the histogram with the
 option "cont3"

 The drawn object (RooPlot or sampled histogram) is saved in teh class and can be retrieved using GetPlottedObject()
 In this way the user can eventually customize further the plot.
 Note that the class does not delete the plotted object. It needs, if needed, to be deleted by the user

void SetRange(double x1, double y1, double x2, double y2)
 set plot range (for 2D plot)
void SetPrecision(double eps)
set plot precision (when drawing a RooPlot)
{ fPrecision = eps; }
