// 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.
