 * - Handlers instances in memory
 * - The expected handler method is always "handle"
 * - And only one command at a time can be executed.
 *
 * This factory is a decent place to start trying out Tactician but you're
 * better off moving to a custom setup or a framework bundle/module/provider in
 * the long run. As you can see, it's not difficult. :)
