crschmidt 7da6a3540e Merge the excellent documentation work done during foss4g into trunk. Many
thanks to all the contributors who helped put this together. 
I'm not exactly sure of what's going to happen with this, but for now,
at http://openlayers.org/dev/doc/examples.html you can see links to all the
examples *with descriptions*. Hooray!
