23 
24 ConfInterval is an interface class for a generic interval in the RooStats framework.
25 Any tool inheriting from IntervalCalculator can return a ConfInterval.
26 There are many types of intervals, they may be a simple range [a,b] in 1 dimension,
27 or they may be disconnected regions in multiple dimensions.
28 So the common interface is simply to ask the interval if a given point "IsInInterval".
29 The Interval also knows what confidence level it was constructed at and the space of
30 parameters for which it was constructed.
31 Note, one could use the same class for a Bayesian "credible interval".
