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

is associated with a type tag, which is how a type is represented in, e.g., SQL storage. Types
can share type tags, because backing SQL storage is able to differentiate between some types
(e.g., longs and doubles), and so distinct tags aren't necessary. That association is defined by
<code>SQLValueType</code>. That trait similarly extends to <code>ValueTypeSet</code>, which maps a collection of types
into a collection of tags.</p>

<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>)
