0.2.5

• ConfidenceInterval can compute Feldman and Cousin intervals with boundaries (i.e qtilde=True)
• AsymptoticCalculator asymov weights are now scaled to the number of entries in dataset from loss function if the loss is not extended
• hepstats.hypotests can now be used even if there is no nuisances. The pll function in utils/fit/diverse.py had to be modified such that if there are no nuisances, the pll function returns the value of the loss function.
• add notebooks demos for FC intervals with the FrequentistCalculator and AsymptoticCalculator.
• add warnings when multiple roots are found in ConfidenceInterval
• move toys .yml files from notebook to notebook/toys
