flydra-sphinx-docs math markup broken

It looks like the docs are correctly built; however, github doesn't like directory names starting with an underscore, so the images are not displayed.

In the scikits.image build process, we use this hack:

sed -i "" 's/_static/static/g' find . -name "*.html" sed -i "" 's/_images/images/g' find . -name "*.html" mv _static static mv _images images

Actually, the problem was that I didn't have dvipng installed on the buildbot slave that was building and uploading the docs. (This is required by sphinx.ext.pngmath.)

The problem is corrected now.
