Enter the name of a Wikipedia page (just the name, not the URL) to get a history flow in SVG.
Note: Pages with an extensive history of edits will cause this script to run very slowly.
For background see blog post Visualising edit history of a Wikipedia page. Inspiration came from Jeff Attwood's post Mixing Oil and Water: Authorship in a Wiki World, which discusses the History Flow project. Makes use of the Text_Diff package.
