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