…nt crash Calling set_topology() with a freshly constructed topology (e.g. pagmo::topology(pagmo::ring())) would replace the archipelago's topology with one having 0 vertices, while the archipelago may already contain islands. Subsequent evolve() would then crash when get_connections() is called with an out-of-bounds vertex index. Fix by adding a num_vertices() method to the topology class and modifying set_topology() to automatically call push_back() until the topology has enough vertices for all existing islands. Fixes esa#606
