HyperPlot, Author: Sam Harnew, sam.h.nosp@m.arne.nosp@m.w@gma.nosp@m.il.c.nosp@m.om , Date: Dec 2015

Algorithm to adaptively create a HyperVolumeBinning for a specific HyperPointSet, taking limits from a HyperCuboid.

Todo:: rememer how this algorithm works - its something along these lines... Fits the points in the bin with a flat line, then fits it with a step fuction (that has 3 free parameters, height before step height after step, and step point ). The step point that maximises the likelihood is chosen as the split point.

Additionally, you can compare the significance of splitting in different dimensions using the likelihood ratio of the flat line and the step function. choose to split in the dimension that gives the biggest significance.
