scikit-learn EuroScipy 2011 coding sprint -- day one

As a warm-up for the upcoming EuroScipy-conference, some of the scikit-learn developers decided to gather and work together for a couple of days. Today was the first day and there was only a handfull of us, as the real kickoff is expected tomorrow. Some interesting coding happened, although most of us where still preparing material for the EuroScipy tutorials ... - API changes: remove of keyword parameters to fit method, added method set_params (pull request 1). - Some bugfixing in NuSVR (pull request 2) - Review of Vlad's code, developed during his Summer of Code program. - A lot of discussion about algorithm, code, APIs and buildbot dance !
