break_up_matrix_term    Sometimes there can be terms in a formula that
                        refer to a matrix instead of a single
                        predictor. Because we can handle search_terms
                        of predictors, this function breaks the matrix
                        term into individual predictors to handle
                        separately, as that is probably the intention
                        of the user.
