        public ItemClassifierSettings​(edu.columbia.tjw.item.ItemSettings settings_,
                              String intercept_,
                              edu.columbia.tjw.item.base.SimpleStatus status_,
                              int maxParamCount_,
                              List<String> regressors_,
                              Set<String> curveRegressors_)
        Use this to construct settings unless you really know what you're doing.
        Parameters:
        settings_ - Item settings to use, can be null.
        intercept_ - Which regressor will be the intercept. You don't need to specify this in the data, it will be assumed to be 1.0 always.
        status_ - Which status are we projecting from (only interesting for markov chains, just make a simple 2 status family if in doubt).
        maxParamCount_ - How many parameters is the model allowed to use. Each curve will use approximately 3 params.
        regressors_ - The list (in order) of the regressors to use. This must be in the same order that they appear in the features column.
        curveRegressors_ - The regressors that can support curves (i.e. they are not binary flags), order doesn't matter for these.
