PSR-4 autoloading

[dustinleblanc]

Hey Folks!

We just pulled this project into a site we're working on and realized that none of the code is namespaced per PSR-4 conventions which makes it a little unconventional to work with. Would you be amenable to a pull-request to move this library over to a full PSR-4 compliant namespacing setup? I believe it shouldn't be too difficult to do as I think there are only a handful of classes here. It may help to promote adoption and make it easier for people to create dependent packages (like a Laravel Package, a Drupal 8 module, etc).

Thanks!

I'd be a fan of these changes. However, CampaignMonitor aren't too quick answering on Github - might be best to also drop their support an email.

Any traction on this? My Drupal codebase fails code style checks because the classes aren't namespaced.

use CS_REST_Subscribers;

Non-namespaced classes/interfaces/traits should not be referenced with use statements

BTW, if this is helpful to anyone else, you can surround the use statement with annotations to tell phpcs to ignore it for now:

// @codingStandardsIgnoreStart
use CS_REST_Subscribers;
// @codingStandardsIgnoreEnd
