Copy
This example demonstrates how to copy all of the vertices and edges from an adjacency list graph g1 to adjacency list graph g2 and adjacency list graph g3 to adjacency list graph g1.
An adjacency-list is a two-dimensional structure, where each element of the first dimension represents a vertex, and each of the vertices contain a one-dimensional structure that is its edge list. The copy_graph function copies all of the vertices and edges from graph g1 into g2 and g3 into g1. Also, it copies the vertex and edge properties by using either, the vertex_all and edge_all property maps, or by user-supplied copy functions. The binary function vertex_copy copies the properties of a vertex in the original graph into the corresponding vertex in the copy.
