Mentat documentation website using Jekyll (#754)
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

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
