Tags give the ability to mark specific points in history as being important
Allow passing function to postprocess; improve uncertainty docstrings
Make ignoring missing variations in readroot work with uproot
Remove hard ROOT dependency of scanroot (and therefore hopefully the package as a whole); allow maths operations between histograms and Numpy arrays
Reimplement converting histograms to ROOT (without root-numpy)
Remove unused code and dodgy circular dependency in readroot
Remove strict ROOT and root-numpy dependency, use uproot instead
Lots of new functionality (including some undocumented...)
Allow setting bin heights to constant scalar, improve heatmap bin texts (smarter zero suppression)
Add (still very bad) documentation of systematic uncertainty tools
Improved histogram functionality, YODA output, better plotting
First PyPI release with working autodoc documentation
First PyPI release with incomplete documentation
