/**
* 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.
