Updated for new Topo API
custom topo: remove author name
No need for this here, especially because this file is in the walkthroughand will be found by web crawlers.
Fix custom topology example; outdated import
Reported-by: Julius Bachnick
rename Topo() methods for consistency: add_node() -> addNode()
Consolidate install script and add cmd-line options
Now, the majority the install can be done with one line, but the otherto each part of the install is still available.
Also fix a few bugs and add Wireshark coloring rules.
Renamed topo_2sw_2host.py -> topo-2sw-2host.py
Still could be better though.... and we need more topologyexamples.
