Remarks
The SNS class allows you to quickly and easily access Amazon's Simple Notification Service (SNS). SNS allows you to create topics and subscriptions for notification purposes.
Before using the class you must first have an AWS account and sign up for the SNS service. To use the class first set AccessKey and SecretKey.
To create a topic call CreateTopic. You may manage the topic and it's properties through GetTopicAttributes, SetTopicAttributes, and DeleteTopic.
To subscribe to a topic call Subscribe. To manage a subscription use GetSubscriptionAttributes, SetSubscriptionAttributes, and Unsubscribe.
Use ListSubscriptions, ListTopicSubscriptions, and ListTopics to list existing topics and subscriptions.
