- 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
