This pull request makes a few additions and changes that make it easier to use this library as the basis for a NIB in an OpenFlow controller:
Add next_hop_via, which returns the link traversed by the hop;
Rename functions that apply to both switches and hosts, i.e., rename ports_of_switch and add_switch_edge to ports_of_node and add_ports_edge, respectively;
Add remove_port function that will remove labels associated with privded node and port; and
Add remove_switch function, which is a thin wrapper around remove_vertex
In addition, this fixes a bug caused by trying catch the wrong exception. This change should have no effect on the external-facing API.
