//       Class : PStatThreadData
// Description : A collection of FrameData structures for
//               recently-received frames within a particular thread.
//               This holds the raw data as reported by the client,
//               and it automatically handles frames received
//               out-of-order or skipped.  You can ask for a
//               particular frame by frame number or time and receive
//               the data for the nearest frame.
