Thanks Ralf. I agree that this code needs more work. If you have the
time I'd appreciate your insight on the patches themselves where you
observe improper variable use, both in type and in attribute, perhaps
you can show one or two examples of patterns to fix.

The copyright issue needs to be clarified by the students. I believe
they just copy-pasted the copyright header block from some other file,
hence the odd dates. I should prefer that they identify which files
they wrote. I looked back through all 3 GSOC projects and could not
find adequate copyright notices on any of the code.
