#' Treat graph as weighted. In other words, do not ignore weights for edges
#' that define them when inserting edges in the graph.
#' A weight of exactly zero removes the edge instead of inserting so its
#' weight is never ignored.
#' Without this parameter defined or for edges that do not have a weight defined,
#' edges are assigned the default value of 1 (one).
#' As an example, reading from a file may define weights (a third column) for
#' some edges (defined in rows, one per row) and not for others. With this
#' parameter defined, the edges that have weights that are not exactly zero,
#' have their weight replaced by the default value.

#' Stops when, on a cycle of the algorithm, the quality is increased by less
#' than the value given in this parameter.

#' Community-Vertex.
#' Boolean parameter that indicates if sending community mapping to a file
#' prints the community first, if true, or the vertex first, if false. See
