* Middleware are the plugins of Tactician. They receive each command that's

* continue the Command processing by passing the command they receive to the
* $next callable, which is essentially the "next" Middleware in the chain.
*
* Depending on where they invoke the $next callable, Middleware can execute
* their custom logic before or after the Command is handled. They can also
* modify, log, or replace the command they receive. The sky's the limit.
