Heyho,

this is my first draft for a class which manages docker networks. With this you can create, remove and check for existance.

I've tried to let the two classes feel quite similar.

Usage:

$network = new DockerNetwork('network-name');

$network->driver('macvlan'); // Allows you to change the driver of the network

$network->create(); // Creates it
$network->remove(); // Removes it
$network->exists(); // Return a bool, whether the network exists

Of course, all of the regular stuff, like changing remote host or setting optional arguments are still in there. Maybe we could refactor it, so that we have a trait which holds the same variables / methods which both uses. But I didn't want to do to much work, in case you don't want this in your package :-)

What I removed though is the ability to create a class instance with a static method, like DockerNetwork::create(……). The problem is, the create method creates the real network in docker and I couldn't come up with a better name for it.

Do you have any ideas?

Thanks in advance! If you don't want this in your package or if I need to something else, please let me know. I've added the README sections and tests.
