Contributor guide
Research direction
Start by inspecting the cuda.parallel Python area and the requested cub::DeviceHistogram API. Compare the existing exposed functionality with that CUB algorithm; done means histogram support is available through cuda.parallel with behavior matching the requested algorithm.
