Amazon S3 File Upload
Leveraged resources from Keith Weaver Repository on GitHub, and YouTube video.
The files for both upload (upload_aws_process.php) and view (get_process.php) can be restricted
by logon credentials and session keys to ensure only users which appropriate access
can upload and view files on the Amazon S3 storage.
