+models that satisfy strong hierarchy: if an interaction coefficient is estimated
+to be nonzero, then its two associated main effects also have nonzero estimated
+coefficients.  Accommodates categorical variables (factors) with arbitrary
+numbers of levels, continuous variables, and combinations thereof.  Implements
+the machinery described in the paper \"Learning interactions via hierarchical
+group-lasso regularization\" (JCGS 2015, Volume 24, Issue 3).
