/**
 <fullname>Amazon Simple Notification Service</fullname><p>Amazon Simple Notification Service (Amazon SNS) is a web service that enables you to build distributed web-enabled applications. Applications can use Amazon SNS to easily push real-time notification messages to interested subscribers over multiple delivery protocols. For more information about this product see <a href="http://aws.amazon.com/sns/">http://aws.amazon.com/sns</a>. For detailed information about Amazon SNS features and their associated API calls, see the <a href="http://docs.aws.amazon.com/sns/latest/dg/">Amazon SNS Developer Guide</a>. </p><p>We also provide SDKs that enable you to access Amazon SNS from your preferred programming language. The SDKs contain functionality that automatically takes care of tasks such as: cryptographically signing your service requests, retrying requests, and handling error responses. For a list of available SDKs, go to <a href="http://aws.amazon.com/tools/">Tools for Amazon Web Services</a>. </p>

 For example, set the default service configuration in `- application:didFinishLaunchingWithOptions:`

        AWSServiceManager.default().defaultServiceConfiguration = configuration
