 * Optional $args contents:
 *
 * - label - Name of the post type shown in the menu. Usually plural. If not set, labels['name'] will be used.
 * - description - A short descriptive summary of what the post type is. Defaults to blank.
 * - public - Whether posts of this type should be shown in the admin UI. Defaults to false.
 * - exclude_from_search - Whether to exclude posts with this post type from search results.
 *     Defaults to true if the type is not public, false if the type is public.
 * - publicly_queryable - Whether post_type queries can be performed from the front page.
 *     Defaults to whatever public is set as.
 * - show_ui - Whether to generate a default UI for managing this post type. Defaults to true
 *     if the type is public, false if the type is not public.
 * - show_in_menu - Where to show the post type in the admin menu. True for a top level menu,
 *     false for no menu, or can be a top level page like 'tools.php' or 'edit.php?post_type=page'.
 *     show_ui must be true.
 * - menu_position - The position in the menu order the post type should appear. Defaults to the bottom.
 * - menu_icon - The url to the icon to be used for this menu. Defaults to use the posts icon.
 * - capability_type - The string to use to build the read, edit, and delete capabilities. Defaults to 'post'.
 *   May be passed as an array to allow for alternative plurals when using this argument as a base to construct the
 *   capabilities, e.g. array('story', 'stories').
 * - capabilities - Array of capabilities for this post type. By default the capability_type is used
 *      as a base to construct capabilities. You can see accepted values in {@link get_post_type_capabilities()}.
 * - map_meta_cap - Whether to use the internal default meta capability handling. Defaults to false.
 * - hierarchical - Whether the post type is hierarchical. Defaults to false.
 * - supports - An alias for calling add_post_type_support() directly. See {@link add_post_type_support()}

 *     Default is no taxonomies. Taxonomies can be registered later with register_taxonomy() or
 *     register_taxonomy_for_object_type().
 * - labels - An array of labels for this post type. By default post labels are used for non-hierarchical
 *     types and page labels for hierarchical ones. You can see accepted values in {@link get_post_type_labels()}.
 * - permalink_epmask - The default rewrite endpoint bitmasks.
 * - has_archive - True to enable post type archives. Will generate the proper rewrite rules if rewrite is enabled.
 * - rewrite - false to prevent rewrite. Defaults to true. Use array('slug'=>$slug) to customize permastruct;
 *     default will use $post_type as slug. Other options include 'with_front', 'feeds', and 'pages'.
 * - query_var - false to prevent queries, or string to value of the query var to use for this post type
 * - can_export - true allows this post type to be exported.
 * - show_in_nav_menus - true makes this post type available for selection in navigation menus.
