How-to use

Hi

Playing with the various versions of the xml.hs is complicated by:

- the way to run the code changes over time, and is not immediately clear.
- the album.xml file is missing when going back in the history

I've solved both by reordering the history (adding album.xml early on), and by adding a xml-README.txt that says how to run the code.

Please pull :). You can merge with no ill effects; your commits are contained in my history as well, so the merge doesn't add any change to the end state over my branch, but it leaves the original history around (someone using gitk or similar should still easily see what to check out to play with) and since other people may have cloned privately already it will lead to less confusion (--hard and --force are evil in such cases).
