/**
 * Redirection capabilities
 *
 * Pre 4.6
 * =======
 * Hook `redirection_role` and return a capability. This gives access to the entire plugin
 *
 * Post 4.6
 * ========
 * Hook `redirection_role` and return a capability for access to the plugin menu. For example `edit_pages` will allow an editor
 * Hook `redirection_capability_check` and return a different capability for each check that needs specific permissions.
 *
 * For example, if you want to give editors access to create redirects, but nothing else:
 *
 * ```php
 * add_filter( 'redirection_capability_check', function( $capability, $permission_name ) {
 *     if ( $permission_name === 'redirection_cap_redirect_manage' || $permission_name === 'redirection_cap_redirect_add' ) {
 *         return $capability;
 *     }
 *
 *     return 'manage_options';
 * } );
 * ```
 *
 * Always default to restrictive and then grant permissions. Don't default to permissive and remove permissions. This way if a new
 * capability is added your users won't automatically be granted access.
 *
 * Capabilities can be filtered with:
 * - `redirection_capability_check( $capability, $permission_name )` - override `$capability` dependant on `$permission_name`
 * - `redirection_capability_pages( $pages )` - filters the list of available pages
 * - `redirection_role( $cap )` - return the role/capability used for overall access to the plugin
 *
 * Note some capabilities may give access to data from others. For example, when viewing a page of redirects via `redirection_cap_redirect_manage`
 * the client will need to access group data.
