gtools-0.9.0 (2017-11-01)

Features

- The plugin now works on OSX
- Online documentation is now available: [gtools.readthedocs.io](http://gtools.readthedocs.io/en/latest/index.html)
- `gcontract` is a fast alternative to `contrast`
- `gtoplevelsof` is a new command that allows the user to glean the most
  common levels of a set of variables.  Similar to `gcontract` with a `gsort`
  of frequency by descending order thereafter, but `gtoplevelsof` does not
  modify the source data and saves a matrix with the results after its run.
- `gdistinct` now saves its results to a matrix when there are multiple
  variables.
- Improved and normalized documentation
