get_neighbor_clustering
                        Returns the neighborhood clustering (i.e.,
                        local transitivity or local clustering
                        coefficient) for all or a subset of nodes in
                        the language network.
get_neighbor_mean       Returns the mean of a neighborhood's attribute
                        for all or a subset of nodes in the language
                        network.
get_neighbor_size       Returns the neighborhood size (i.e., degree)
                        for all or a subset of nodes in the language
                        network.
get_network_info        Returns a summary of global network
                        characteristics of the language network.
make_network            Create a language network from a list of items.
                        This version takes each single character as an
                        individual segment when specifying neighbors.
make_network_sep        Create a language network from a list of items.
                        This version segments items based on a
                        specified separator when specifying neighbors.
