    Fixed parameter rounding (now uses Math.rint() so that, for example, -1 is not rounded to 0.
classifiers/meta/CVParameterSelection.html (1.27.2.4)
2008-05-16 04:19 mhall
    Deleted all package names from file name of the saved file because the length of file names was getting out of hand (especially when a lot of filters are in the flow)

    - getOptions returned m_DesignatedClass instead of m_ClassMode
classifiers/meta/ThresholdSelector.html (1.30.2.3)
