/**
 * <p>
 * Event within a workflow execution. A history event can be one of these types:
 * </p>
 * <ul>
 * <li><b>WorkflowExecutionStarted</b>: The workflow execution was started.</li>
 * <li><b>WorkflowExecutionCompleted</b>: The workflow execution was closed due to successful completion.</li>
 * <li><b>WorkflowExecutionFailed</b>: The workflow execution closed due to a failure.</li>
 * <li><b>WorkflowExecutionTimedOut</b>: The workflow execution was closed because a time out was exceeded.</li>
 * <li><b>WorkflowExecutionCanceled</b>: The workflow execution was successfully canceled and closed.</li>
 * <li><b>WorkflowExecutionTerminated</b>: The workflow execution was terminated.</li>
 * <li><b>WorkflowExecutionContinuedAsNew</b>: The workflow execution was closed and a new execution of the same type
 * was created with the same workflowId.</li>
 * <li><b>WorkflowExecutionCancelRequested</b>: A request to cancel this workflow execution was made.</li>
 * <li><b>DecisionTaskScheduled</b>: A decision task was scheduled for the workflow execution.</li>
 * <li><b>DecisionTaskStarted</b>: The decision task was dispatched to a decider.</li>
 * <li><b>DecisionTaskCompleted</b>: The decider successfully completed a decision task by calling
 * <a>RespondDecisionTaskCompleted</a>.</li>
 * <li><b>DecisionTaskTimedOut</b>: The decision task timed out.</li>
 * <li><b>ActivityTaskScheduled</b>: An activity task was scheduled for execution.</li>
 * <li><b>ScheduleActivityTaskFailed</b>: Failed to process ScheduleActivityTask decision. This happens when the
 * decision is not configured properly, for example the activity type specified is not registered.</li>
 * <li><b>ActivityTaskStarted</b>: The scheduled activity task was dispatched to a worker.</li>
 * <li><b>ActivityTaskCompleted</b>: An activity worker successfully completed an activity task by calling
 * <a>RespondActivityTaskCompleted</a>.</li>
 * <li><b>ActivityTaskFailed</b>: An activity worker failed an activity task by calling
 * <a>RespondActivityTaskFailed</a>.</li>
 * <li><b>ActivityTaskTimedOut</b>: The activity task timed out.</li>
 * <li><b>ActivityTaskCanceled</b>: The activity task was successfully canceled.</li>
 * <li><b>ActivityTaskCancelRequested</b>: A <code>RequestCancelActivityTask</code> decision was received by the system.
 * </li>
 * <li><b>RequestCancelActivityTaskFailed</b>: Failed to process RequestCancelActivityTask decision. This happens when
 * the decision is not configured properly.</li>
 * <li><b>WorkflowExecutionSignaled</b>: An external signal was received for the workflow execution.</li>
 * <li><b>MarkerRecorded</b>: A marker was recorded in the workflow history as the result of a <code>RecordMarker</code>
 * decision.</li>
 * <li><b>TimerStarted</b>: A timer was started for the workflow execution due to a <code>StartTimer</code> decision.</li>
 * <li><b>StartTimerFailed</b>: Failed to process StartTimer decision. This happens when the decision is not configured
 * properly, for example a timer already exists with the specified timer ID.</li>
 * <li><b>TimerFired</b>: A timer, previously started for this workflow execution, fired.</li>
 * <li><b>TimerCanceled</b>: A timer, previously started for this workflow execution, was successfully canceled.</li>
 * <li><b>CancelTimerFailed</b>: Failed to process CancelTimer decision. This happens when the decision is not
 * configured properly, for example no timer exists with the specified timer ID.</li>
 * <li><b>StartChildWorkflowExecutionInitiated</b>: A request was made to start a child workflow execution.</li>
 * <li><b>StartChildWorkflowExecutionFailed</b>: Failed to process StartChildWorkflowExecution decision. This happens
 * when the decision is not configured properly, for example the workflow type specified is not registered.</li>
 * <li><b>ChildWorkflowExecutionStarted</b>: A child workflow execution was successfully started.</li>
 * <li><b>ChildWorkflowExecutionCompleted</b>: A child workflow execution, started by this workflow execution, completed
 * successfully and was closed.</li>
 * <li><b>ChildWorkflowExecutionFailed</b>: A child workflow execution, started by this workflow execution, failed to

 * <li><b>ChildWorkflowExecutionTerminated</b>: A child workflow execution, started by this workflow execution, was
 * terminated.</li>
 * <li><b>SignalExternalWorkflowExecutionInitiated</b>: A request to signal an external workflow was made.</li>
 * <li><b>ExternalWorkflowExecutionSignaled</b>: A signal, requested by this workflow execution, was successfully
 * delivered to the target external workflow execution.</li>
 * <li><b>SignalExternalWorkflowExecutionFailed</b>: The request to signal an external workflow execution failed.</li>
 * <li><b>RequestCancelExternalWorkflowExecutionInitiated</b>: A request was made to request the cancellation of an
 * external workflow execution.</li>
 * <li><b>ExternalWorkflowExecutionCancelRequested</b>: Request to cancel an external workflow execution was
 * successfully delivered to the target execution.</li>
 * <li><b>RequestCancelExternalWorkflowExecutionFailed</b>: Request to cancel an external workflow execution failed.</li>
 * <li><b>LambdaFunctionScheduled</b>: An AWS Lambda function was scheduled for execution.</li>
 * <li><b>LambdaFunctionStarted</b>: The scheduled function was invoked in the AWS Lambda service.</li>
 * <li><b>LambdaFunctionCompleted</b>: The AWS Lambda function successfully completed.</li>
 * <li><b>LambdaFunctionFailed</b>: The AWS Lambda function execution failed.</li>
 * <li><b>LambdaFunctionTimedOut</b>: The AWS Lambda function execution timed out.</li>
 * <li><b>ScheduleLambdaFunctionFailed</b>: Failed to process ScheduleLambdaFunction decision. This happens when the
 * workflow execution does not have the proper IAM role attached to invoke AWS Lambda functions.</li>
 * <li><b>StartLambdaFunctionFailed</b>: Failed to invoke the scheduled function in the AWS Lambda service. This happens
 * when the AWS Lambda service is not available in the current region, or received too many requests.</li>
