22Class RooBinningCategory provides a real-to-category mapping defined
23by a series of thresholds. It evaluates the value of `inputVar` passed in the
24constructor, and converts this into a bin number using a binning defined for
25the inputVar. The name of this binning is passed in the constructor.
