// Gets the path tracking results of a Amazon Rekognition Video analysis started by
// StartPersonTracking. The person path tracking operation is started by a call to
// StartPersonTracking which returns a job identifier (JobId). When the operation
// finishes, Amazon Rekognition Video publishes a completion status to the Amazon
// Simple Notification Service topic registered in the initial call to
// StartPersonTracking. To get the results of the person path tracking operation,
// first check that the status value published to the Amazon SNS topic is
// SUCCEEDED. If so, call GetPersonTracking and pass the job identifier (JobId)
// from the initial call to StartPersonTracking. GetPersonTracking returns an
// array, Persons, of tracked persons and the time(s) their paths were tracked in
// the video. GetPersonTracking only returns the default
//
// facial attributes
// (BoundingBox, Confidence, Landmarks, Pose, and Quality). The other facial
// attributes listed in the Face object of the following response syntax are not
// returned. For more information, see FaceDetail in the Amazon Rekognition
// Developer Guide. By default, the array is sorted by the time(s) a person's path
// is tracked in the video. You can sort by tracked persons by specifying INDEX for
// the SortBy input parameter. Use the MaxResults parameter to limit the number of
// items returned. If there are more results than specified in MaxResults, the
// value of NextToken in the operation response contains a pagination token for
// getting the next set of results. To get the next page of results, call
// GetPersonTracking and populate the NextToken request parameter with the token
// value returned from the previous call to GetPersonTracking.
