Pseudo-elegant way to flush rewrite rules after creating a custom post type.
<?php

* Example for writing a WP plugin that adds a custom post type and flushes
* rewrite rules only once on initialization.
*/
/**
* On activation, we'll set an option called 'my_plugin_name_flush' to true,
* so our plugin knows, on initialization, to flush the rewrite rules.
*/

/**
* On deactivation, we'll remove our 'my_plugin_name_flush' option if it is
* still around. It shouldn't be after we register our post type.
*/

/**
* Register our post type. Specifically, we'll check if our
* 'my_plugin_name_flush' option is true. If so, we'll flush the rewrite rules,
* then delete the option, so it only flushes the rules once.
