/** \class LiThresholdCalculator
* \brief Computes the Li threshold for an image. Aka intermeans
*
* Implements Li's Minimum Cross Entropy thresholding method
* This implementation is based on the iterative version (Ref. 2) of the algorithm.

* Pattern Recognition, 26(4): 617-625

* Cross Entropy Thresholding"Pattern Recognition Letters, 18(8): 771-776

*
* This class is templated over the input histogram type.
* \warning This calculator assumes that the input histogram has only one dimension.
