/**

 * Amazon Simple Workflow Service (SWF) is an orchestration service for building scalable,

 * resilient applications. Using Amazon SWF, developers can structure the various processing steps

 * in an application as tasks that drive independent, distributed components and orchestrate these

 * tasks in a reliable and scalable manner.

 *

 * The flow for a typical Amazon SWF application is to use long-running processes which are

 * handled by the PHP executable directly, instead of being part of the common web server

 * request/response cycle that PHP developers are typically more familiar with.

 *

 * <strong>Managing a scalable workflow:</strong>

 *

 * <ol>

 * 	<li>Create a workflow domain to work within.</li>

 * 	<li>Register any Workflow Types and Activity Types that are relevant to your workflow.</li>

 * 	<li>Start your Workflow Execution.</li>

 * 	<li>Poll for decisions that need to be made and respond to them.</li>

 * 	<li>Poll for activities that a particular state of completion (successful, failure, canceled,

 * in-progress), and respond to them.</li>

 * </ol>

 *

 * Once a Workflow has been configured and execution has started, the acts of polling for

 * decisions and polling for activities follow an event-driven programming model. Since PHP's

 * interpreter is single-threaded, entering into event loops for polling decisions and activities

 * simultaneously requires two separate PHP processes to be running.
