Support per-node, arbitrary actions at different points during an experiment.
There is currently no elegant way to differentiate nodes during an experiment. For example, setting up certificates for an experiment using auto-prefix propagation requires complicated logic in the experiment file.
Instead, it should be possible to identify setup "bookmarks", such as router onlining, NLSR startup, experiment start, etc., at which you can specify arbitrary actions. This would make setting up topologies with complicated inter-node relationships easier.
