set_vertex_color takes an integer vector (representing membership of
a community or component, etc.) and creates a character vector of colors for
each community/module, component, etc. This only assigns a color to groups
with at least 2 members; isolated vertices will be colored gray. set_edge_color additionally takes as input an igraph graph
object. It assigns to the edges a specific color (the same as the vertex
membership colors). Edges that connect vertices of two different groups are
colored gray.set_vertex_color(memb)set_edge_color(g, memb)
