Mock AWS S3 SDK

This is a very simple interface that mocks the AWS SDK for Node.js. The implementation is incomplete but most basic features are supported.

Available:

createBucket
deleteBucket
listObjects
listObjectsV2
deleteObjects
deleteObject
getObject
headObject
putObject
copyObject
getObjectTagging
putObjectTagging
upload

It uses a directory to mock a bucket and its content.

If you'd like to see some more features or you have some suggestions, feel free to use the issues or submit a pull request.
