A PHP abstract class that will automatically register all methods as a wordpress action or filter

Autohook.php

<?php
/**
 * When a class extends this, this will use PHP reflection to automatically register actions and filters
 * Note that this class cannot be instantiated, it is marked as abstract
 *
 * In order to add a method as a filter, simply name it as `filter_FILTERNAME`. For example: `filter_body_class` will add that method as a hook for the filter 'body class'
 * The same applies to actions, but the naming changes to `action_ACTIONNAME`. For example: `action_widgets_init`
