N5 library implementation using Amazon Web Services S3 backend.

N5 containers can be represented by either an S3 bucket, or a path (directory) within a bucket.

Access to non-public buckets requires a few steps to set up the security credentials:

1. Create access keys in the AWS console.
2. Configure them on your machine using the credentials profile:
   • Install AWS Command Line Interface.
   • Run aws configure and enter your access key ID, secret key, and geographical region as described here.
