SDK License missing

[EliW]

It appears that the LICENSE file is missing from this particular library, as it exists in all the other language SDK's that CyberSource provides ... including the PHP SOAP SDK: https://github.com/CyberSource/cybersource-sdk-php/blob/master/LICENSE

It would appear, I assume, that this is an oversight. However before we continue moving forward in using this client. It would be good for the license to be merged/copied into this Client Library as well, giving people permission to use it properly.

Thanks

Tagging @gnongsie for awareness, since you appear to be the only one who makes commits here. And this should hopefully be a 30 second fix to just copy the license file into this repo. Thanks.
