/**
* Client for accessing AWS SFN. All service calls made using this client are blocking, and will not return until the
* service call completes.
* <p>
* <fullname>AWS Step Functions</fullname>
* <p>
* AWS Step Functions is a web service that enables you to coordinate the components of distributed applications and
* microservices using visual workflows. You build applications from individual components that each perform a discrete
* function, or <i>task</i>, allowing you to scale and change applications quickly. Step Functions provides a graphical
* console to visualize the components of your application as a series of steps. It automatically triggers and tracks
* each step, and retries when there are errors, so your application executes in order and as expected, every time. Step
* Functions logs the state of each step, so when things do go wrong, you can diagnose and debug problems quickly.
* </p>
* <p>
* Step Functions manages the operations and underlying infrastructure for you to ensure your application is available
* at any scale. You can run tasks on the AWS cloud, on your own servers, or an any system that has access to AWS. Step
* Functions can be accessed and used with the Step Functions console, the AWS SDKs (included with your Beta release
* invitation email), or an HTTP API (the subject of this document).
* </p>
