class RooStats::HypoTestInverter: public RooStats::IntervalCalculator, public TNamed

   HypoTestInverter class for performing an hypothesis test inversion by scanning the hypothesis test results of the
  HybridCalculator  for various values of the parameter of interest. By looking at the confidence level curve of
 the result  an upper limit, where it intersects the desired confidence level, can be derived.
 The class implements the RooStats::IntervalCalculator interface and returns an  RooStats::HypoTestInverterResult class.
 The result is a SimpleInterval, which via the method UpperLimit returns to the user the upper limit value.

The  HypoTestInverter implements various option for performing the scan. HypoTestInverter::RunFixedScan will scan using a fixed grid the parameter of interest. HypoTestInverter::RunAutoScan will perform an automatic scan to find optimally the curve and it will stop until the desired precision is obtained.
The confidence level value at a given point can be done via  HypoTestInverter::RunOnePoint.
The class can scan the CLs+b values or alternativly CLs (if the method HypoTestInverter::UseCLs has been called).
