/**
 * The Amazon Simple Workflow Service API Reference is intended for programmers who need detailed
 * information about the Amazon SWF actions and data types.
 *  
 * For an broader overview of the Amazon SWF programming model, please go to the <a href=
 * "http://docs.amazonwebservices.com/amazonswf/latest/developerguide/">Amazon SWF Developer
 * Guide</a>.
 *  
 * This section provides an overview of Amazon SWF actions.
 *  
 * <strong>Action Categories</strong>
 *  
 * The Amazon SWF actions can be grouped into the following major categories.
 * 
 * <ul>
 * 	<li>Actions related to Activities</li>
 * 	<li>Actions related to Deciders</li>
 * 	<li>Actions related to Workflow Executions</li>
 * 	<li>Actions related to Administration</li>
 * 	<li>Actions related to Visibility</li>
 * </ul>
 * 
 * <strong>Actions related to Activities</strong>
 *  
 * The following are actions that are performed by activity workers:
 * 
 * <ul>
 * 	<li><a href="API_PollForActivityTask.html" title=
 * 		"PollForActivityTask">PollForActivityTask</a></li>
 * 	<li><a href="API_RespondActivityTaskCompleted.html" title=
 * 		"RespondActivityTaskCompleted">RespondActivityTaskCompleted</a></li>
 * 	<li><a href="API_RespondActivityTaskFailed.html" title=
 * 		"RespondActivityTaskFailed">RespondActivityTaskFailed</a></li>
 * 	<li><a href="API_RespondActivityTaskCanceled.html" title=
 * 		"RespondActivityTaskCanceled">RespondActivityTaskCanceled</a></li>
 * 	<li><a href="API_RecordActivityTaskHeartbeat.html" title=
 * 		"RecordActivityTaskHeartbeat">RecordActivityTaskHeartbeat</a></li>
 * </ul>
 * 
 * Activity workers use the <a href="API_PollForActivityTask.html" title=
 * "PollForActivityTask">PollForActivityTask</a> to get new activity tasks. After a worker
 * receives an activity task from Amazon SWF, it performs the task and responds using <a href=
 * "API_RespondActivityTaskCompleted.html" title=
 * "RespondActivityTaskCompleted">RespondActivityTaskCompleted</a> if successful or <a href=
 * "API_RespondActivityTaskFailed.html" title=
 * "RespondActivityTaskFailed">RespondActivityTaskFailed</a> if unsuccessful.
 *  
 * <strong>Actions related to Deciders</strong>
 *  
 * The following are actions that are performed by deciders:
 * 
 * <ul>
 * 	<li><a href="API_PollForDecisionTask.html" title=
 * 		"PollForDecisionTask">PollForDecisionTask</a></li>
 * 	<li><a href="API_RespondDecisionTaskCompleted.html" title=
 * 		"RespondDecisionTaskCompleted">RespondDecisionTaskCompleted</a></li>
 * </ul>
 * 
 * Deciders use <a href="API_PollForDecisionTask.html" title=
 * "PollForDecisionTask">PollForDecisionTask</a> to get decision tasks. After a decider receives a
 * decision task from Amazon SWF, it examines its workflow execution history and decides what to
 * do next. It calls <a href="API_RespondDecisionTaskCompleted.html" title=
 * "RespondDecisionTaskCompleted">RespondDecisionTaskCompleted</a> to complete the decision task
 * and provide zero or more next decisions.
 *  
 * <strong>Actions related to Workflow Executions</strong>
 *  
 * The following actions operate on a workflow execution:
 * 
 * <ul>
 * 	<li><a href="API_RequestCancelWorkflowExecution.html" title=
 * 		"RequestCancelWorkflowExecution">RequestCancelWorkflowExecution</a></li>
 * 	<li><a href="API_StartWorkflowExecution.html" title=
 * 		"StartWorkflowExecution">StartWorkflowExecution</a></li>
 * 	<li><a href="API_SignalWorkflowExecution.html" title=
 * 		"SignalWorkflowExecution">SignalWorkflowExecution</a></li>
 * 	<li><a href="API_TerminateWorkflowExecution.html" title=
 * 		"TerminateWorkflowExecution">TerminateWorkflowExecution</a></li>
 * </ul>
 * 
 * <strong>Actions related to Administration</strong>
 *  
 * Although you can perform administrative tasks from the Amazon SWF console, you can use the
 * actions in this section to automate functions or build your own administrative tools.
 *  
 * <strong>Activity Management</strong>
 * 
 * <ul>
 * 	<li><a href="API_RegisterActivityType.html" title=
 * 		"RegisterActivityType">RegisterActivityType</a></li>
 * 	<li><a href="API_DeprecateActivityType.html" title=
 * 		"DeprecateActivityType">DeprecateActivityType</a></li>
 * </ul>
 * 
 * <strong>Workflow Management</strong>
 * 
 * <ul>
 * 	<li><a href="API_RegisterWorkflowType.html" title=
 * 		"RegisterWorkflowType">RegisterWorkflowType</a></li>
 * 	<li><a href="API_DeprecateWorkflowType.html" title=
 * 		"DeprecateWorkflowType">DeprecateWorkflowType</a></li>
 * </ul>
 * 
 * <strong>Domain Management</strong>
 * 
 * <ul>
 * 	<li><a href="API_RegisterDomain.html" title="RegisterDomain">RegisterDomain</a></li>
 * 	<li><a href="API_DeprecateDomain.html" title="DeprecateDomain">DeprecateDomain</a></li>
 * </ul>
 * 
 * <strong>Workflow Execution Management</strong>
 * 
 * <ul>
 * 	<li><a href="API_RequestCancelWorkflowExecution.html" title=
 * 		"RequestCancelWorkflowExecution">RequestCancelWorkflowExecution</a></li>
 * 	<li><a href="API_TerminateWorkflowExecution.html" title=
 * 		"TerminateWorkflowExecution">TerminateWorkflowExecution</a></li>
 * </ul>
 * 
 * <strong>Visibility Actions</strong>
 *  
 * Although you can perform visibility actions from the Amazon SWF console, you can use the
 * actions in this section to build your own console or administrative tools.
 *  
 * <strong>Activity Visibility</strong>
 * 
 * <ul>
 * 	<li><a href="API_ListActivityTypes.html" title="ListActivities">ListActivityTypes</a></li>
 * 	<li><a href="API_DescribeActivityType.html" title=
 * 		"DescribeActivityType">DescribeActivity</a></li>
