0.9.9: Merge pull request #462 from reneeotten/documentation_docstrings
This release provides a few small but important changes compared to 0.9.8:
- asteval is now required as a separate install -- a copy is no longer included in lmfit. This makes it easier for asteval developments to happen independently from lmfit.
- the formatting of floating point numbers in the fit report is now better, fixing at least one bug where the values reported were truncated and incorrect.
- prefixes of Model components can be changed after the model is created.
- saving models and modelresults can now include user-specified data (as long as it can be converted to json!).
