Steps to building docs locally:
1. Install Jekyll
2. cd docs
3. bundle exec jekyll serve --incremental
4. open local docs site at http://127.0.0.1:4000/
* basic Jekyll site
* Add docs to documentation site
* Update javadoc to allow for error free builds
* Remove docs for rust dependencies
* Better display examples, about and contributing documentation for Mentat
* Version docs
