Walk the Neighborhood

I (Ward) suggest I rewrite the program in to distinct parts: `lineup` and `history`. With each iteration the monkey `clicks` a link from the lineup not yet in history. When the monkey exhausts the available links or otherwise tires, the history has enough information to `graph` the choices made as a tree. The monkey will need methods to recognize various kinds of `links` and to heuristically `choose` from these possibilities respecting writing and browssing conventions unique to a particular wiki. element github
