Create at least one real-world swagmap

[limikael]

The "physical" map in the hotspot image at http://coding.tunapanda.org/ seems like a good choice to start with.

For an example of the currently supported format, see the ktouch example map, but as far as I know, changes can still be proposed to that format. For example, we probably don't want to have to manually specify x/y coordinates for each point on the map.

During today's call, we started a document to draft schemas for swagmaps and related structures (swagifacts, etc). It still needs work, and this seems like a sensible place to track that work (if anyone disagrees, let me know and I will move it to a separate issue).
