Class encapsulating the result of the HybridCalculatorOriginal.

This class is a fresh rewrite in RooStats of RooStatsCms/LimitResults developed by D. Piparo and G. Schott New contributions to this class have been written by Matthias Wolf (error estimation)

The objects of this class store and access with lightweight methods the information calculated by LimitResults through a Lent calculation using MC toy experiments. In some ways can be considered an extended and extensible implementation of TConfidenceLevel.
