%description
Computes optimal changepoint models using the Poisson likelihood for
non-negative count data, subject to the PeakSeg constraint: the first
change must be up, second change down, third change up, etc. For more info
about the models and algorithms, read "Constrained Dynamic Programming and
Supervised Penalty Learning Algorithms for Peak Detection"
