-This is a package meant primarily for documenting histogram indexing and the PlottableProtocol and any future cross-library standards. It also contains the code for the PlottableProtocol, to be used in type checking libraries wanting to conform to the protocol. Eventually, it might gain a set of tools for testing conformance to UHI indexing, as well. It is not intended to be a runtime dependency, but only a type checking, testing, and/or docs dependency in support of our other libraries (boost-histogram, hist, mplhep, histoprint). It requires Python 3.6+.
