95% circles

[ctwardy]

Add 25%, 50%, 75%, and 95% circles on the test image, just for show.

First version: use "Hiker" or overall average distances.
Second version: use the ones for the correct class.
??Third version: use a Bayes net model??

OK: Nathan says the Google API doesn't support circles, so it has to be a polygon with (16? 32? 64?) points, in LatLong. We can't just take the image and add our own stuff, because of the license terms.

How about we ask Google for permission?

This might be a good task for Mukul, who knows several annotation libraries.
