Guided tour of Pathalizer - How it Works

Basically, Pathalizer converts a list of hits (with referer field) into a collection of pairs. Then, those pairs are used to generate the resulting graph. 2 examples:
url: bar, referrer: foo
url: baz, referrer: bar
Trivial case.
url: bar, referrer: foo
url: baz, referrer: foo
This is obviously kindof heuristic, but probably models the users' behaviour best (as he probably used tabbed browsing or the 'back' button). It's suboptimal, but I think it's the best we can do by looking only at the logging.
