//   CancelTimer: cancels a previously started timer and records a TimerCanceled
// event in the history.  CancelWorkflowExecution: closes the workflow execution

// closes the workflow execution and records a WorkflowExecutionCompleted event
// in the history .  ContinueAsNewWorkflowExecution: closes the workflow execution
// and starts a new workflow execution of the same type using the same workflow
// ID and a unique run ID. A WorkflowExecutionContinuedAsNew event is recorded
// in the history.  FailWorkflowExecution: closes the workflow execution and
// records a WorkflowExecutionFailed event in the history.  RecordMarker: records
// a MarkerRecorded event in the history. Markers can be used for adding custom
// information in the history for instance to let deciders know that they do
// not need to look at the history beyond the marker event.  RequestCancelActivityTask:
// attempts to cancel a previously scheduled activity task. If the activity
// task was scheduled but has not been assigned to a worker, then it will be
// canceled. If the activity task was already assigned to a worker, then the
// worker will be informed that cancellation has been requested in the response
// to RecordActivityTaskHeartbeat.  RequestCancelExternalWorkflowExecution:
// requests that a request be made to cancel the specified external workflow
// execution and records a RequestCancelExternalWorkflowExecutionInitiated event
// in the history.  ScheduleActivityTask: schedules an activity task.  ScheduleLambdaFunction:
// schedules a AWS Lambda function.  SignalExternalWorkflowExecution: requests
// a signal to be delivered to the specified external workflow execution and
// records a SignalExternalWorkflowExecutionInitiated event in the history.
//  StartChildWorkflowExecution: requests that a child workflow execution be
// started and records a StartChildWorkflowExecutionInitiated event in the history.
// The child workflow execution is a separate workflow execution with its own
// history.  StartTimer: starts a timer for this workflow execution and records
// a TimerStarted event in the history. This timer will fire after the specified
// delay and record a TimerFired event.  Access Control
//
// If you grant permission to use RespondDecisionTaskCompleted, you can use
// IAM policies to express permissions for the list of decisions returned by

//
// Decision Failure
//
// Decisions can fail for several reasons
//
//  The ordering of decisions should follow a logical flow. Some decisions
// might not make sense in the current context of the workflow execution and
// will therefore fail. A limit on your account was reached. The decision lacks
// sufficient permissions.  One of the following events might be added to the
// history to indicate an error. The event attribute's cause parameter indicates
// the cause. If cause is set to OPERATION_NOT_PERMITTED, the decision failed
// because it lacked sufficient permissions. For details and example IAM policies,
// see Using IAM to Manage Access to Amazon SWF Workflows (http://docs.aws.amazon.com/amazonswf/latest/developerguide/swf-dev-iam.html).
//
//   ScheduleActivityTaskFailed: a ScheduleActivityTask decision failed. This
// could happen if the activity type specified in the decision is not registered,
// is in a deprecated state, or the decision is not properly configured.  ScheduleLambdaFunctionFailed:
// a ScheduleLambdaFunctionFailed decision failed. This could happen if the
// AWS Lambda function specified in the decision does not exist, or the AWS
// Lambda service's limits are exceeded.  RequestCancelActivityTaskFailed: a
// RequestCancelActivityTask decision failed. This could happen if there is
// no open activity task with the specified activityId.  StartTimerFailed: a
// StartTimer decision failed. This could happen if there is another open timer
// with the same timerId.  CancelTimerFailed: a CancelTimer decision failed.
// This could happen if there is no open timer with the specified timerId.
// StartChildWorkflowExecutionFailed: a StartChildWorkflowExecution decision
// failed. This could happen if the workflow type specified is not registered,
// is deprecated, or the decision is not properly configured.  SignalExternalWorkflowExecutionFailed:
// a SignalExternalWorkflowExecution decision failed. This could happen if the
// workflowID specified in the decision was incorrect.  RequestCancelExternalWorkflowExecutionFailed:
// a RequestCancelExternalWorkflowExecution decision failed. This could happen
// if the workflowID specified in the decision was incorrect.  CancelWorkflowExecutionFailed:
// a CancelWorkflowExecution decision failed. This could happen if there is
// an unhandled decision task pending in the workflow execution.  CompleteWorkflowExecutionFailed:
// a CompleteWorkflowExecution decision failed. This could happen if there is
// an unhandled decision task pending in the workflow execution.  ContinueAsNewWorkflowExecutionFailed:
// a ContinueAsNewWorkflowExecution decision failed. This could happen if there
// is an unhandled decision task pending in the workflow execution or the ContinueAsNewWorkflowExecution
// decision was not configured correctly.  FailWorkflowExecutionFailed: a FailWorkflowExecution
// decision failed. This could happen if there is an unhandled decision task
// pending in the workflow execution.  The preceding error events might occur
// due to an error in the decider logic, which might put the workflow execution
// in an unstable state The cause field in the event structure for the error
// event indicates the cause of the error.
//
// A workflow execution may be closed by the decider by returning one of the
// following decisions when completing a decision task: CompleteWorkflowExecution,
// FailWorkflowExecution, CancelWorkflowExecution and ContinueAsNewWorkflowExecution.
// An UnhandledDecision fault will be returned if a workflow closing decision
// is specified and a signal or activity event had been added to the history
// while the decision task was being performed by the decider. Unlike the above
// situations which are logic issues, this fault is always possible because
// of race conditions in a distributed system. The right action here is to call
// RespondDecisionTaskCompleted without any decisions. This would result in
// another decision task with these new events included in the history. The
// decider should handle the new events and may decide to close the workflow
// execution. How to code a decision
//
// You code a decision by first setting the decision type field to one of the
// above decision values, and then set the corresponding attributes field shown
