You can hit the 'raw' link, which shows you this page:
http://github.com/mdoube/BoneJ/raw/master/src/org/doube/geometry/FitEllipse.java

Or download the whole source of the BoneJ project by hitting the
download source button (you can choose the latest commit of master or
one of the older tagged versions)
http://github.com/mdoube/BoneJ/archives/master

If anyone can help fix the Taubin method your suggestions are very
welcome; the original MATLAB code is here:
