[Tim Menzies]

how to work out where to split a set of numbers using that entropy
trick we discussed on thursday:

p.s. note that a "real" divider applies the extra entropy culling
rules of section 3.3. of

wriggle is actually necessary

version2 of the entropy thing. now this code implements the Fayyad
and Irani MDL discretizer of numerics as described in Supervised and
Unsupervised Discretization of Continuous Features, James Dougherty,
Ron Kohavi, Mehran Sahami, ICML'95
