Subject: - Fitting and summaries now work with the new parameter
 transformations. - The SFORB models with metabolites is broken (see TODO) -
 Moved the vignette to the location recommended since R 2.14 - Added the
 missing documentation - Commented out the schaefer_complex_case test, as this
 version of   mkin is not able to fit a model without sink and therefore  
 mkin estimated parameters are quite different
