SNS

Example:

sns = Sns.new(aws_access_key, aws_secret_key)
topic = sns.topic('arn:aws:sns:us-east-1:123456789012:test')
topic.subscribe('email', 'someone@example.com')
topic.publish('Hello', 'World')

This is not a complete implementation of the SNS API. Currently only the subscribe and publish actions are supported.
