Plugin in detail

A plugin should extend Mascame\Artificer\Plugin\AbstractPlugin
Lets review an extension in depth:
<?php namespace NamespaceHere;

use Mascame\Artificer\Plugin\AbstractPlugin;

class MyPlugin extends AbstractPlugin {

    /**
     * Automatically filled.
     *
     * Namespace will automatically be set if empty (will usually be the class itself).
     * Example: "Mascame\Artificer\Extension\Extension"
     *
     * @var string
     */
