Please add LICENSE file #11
Description
Some downstream projects insist that all libraries used have stand-alone license files regardless of a specified license in a readme file or composer.json file. The latest phpdocumentor/phpdocumentor v2 (2.9.0) requires "cilex/cilex": "~1.0" and the latest cilex/cilex v1 (1.1.0) requires "cilex/console-service-provider": "1.*".
