Add a table description for preprocessing models such as discretize

JEdward

It would be good to add a table describing the actions of the preprocessing model generated by the discretization operators.

When a discretization model is created and then stored in the repository it is not obvious what transformation the model will perform on data. Only the attributes that are affected.

May I suggest something like this?

attribute	value	min	max
att_1	range1	-Infinity	12
att_1	range2	13	Infinity
att_2	range1	-Infinity	24
att_1	range2	25	Infinity

It would really help for making the preprocessing model more portable and easy to extract into reports explainable to the wider business.

(Current workaround is aggregate results of the discretization column, but it's clunky).
