Using EvaporateJS with AWS V4 Signatures

To get this code working, you'll need to setup your S3 bucket first (see the README). You'll also need to change this file's Evaporate.create() call:

• aws_key -- change this to your AWS_ACCESS_KEY_ID
• awsRegion -- change if your bucket is not us-east-1
• bucket -- set this to your actual bucket name
