* Instances must be sorted by the Attribute used for ChiMerge before Build() is called. This effectively limits ChiMerge to operating on one Attribute at a time. This is a bug. Use multiple ChiMerge filters if further discretisation is needed.
* `NewChiMergeFilter` is used to generate the filter. The second argument is the significance level (in this case 90%). Chi-Merge won't merge adjacent bins if the Chi-Merge statistic is outside of the confidence level indicated by this significance threshold.
* `Build` computes the Chi-Merge bins
* `Run` discretises a set of Instances in place. If a value is lower than or higher than the lowest or highest training value seen, it's assigned the lowest or highest bin.
