It was brought to my attention shortly after releasing this plugin that WordPress automatically flushes 
rewrite rules when you visit WP-Admin > Settings > Permalinks. Ingenious, right? So don’t bother installing it, 
but feel free to check out the code if you are looking for an example of how to:
<ol>
<li>Use the WordPress Settings API to add an option to an existing Settings page;</li>
<li>Use the WordPress AJAX API in conjunction with your plugin options;</li>
<li>Over-engineer a solution to a problem that has already been solved.</li>
</ol>
Enjoy! 🙂

Rewrite Flush Button

Adds a "Flush Rewrite Rules" button to WP-Admin > Settings > Permalinks.
