Flag models with identical search output

[gdcutting]

"If two different models have exactly the same values in Search output, Occam should flag this somehow, since this is inherently anomalous. It could mean, for example, that two different IVs actually map 1:1 to one another, so one of them should be removed. Something like this could also occur is the cardinality of one of the IVs is 1."
