================================================
A simple class to handle simple predictable values
on multiplayer clients.
The class encapsulates the actual value to be stored
as well as the client frame number on which it is set.
When reading predicted values from a snapshot, the actual
value is only updated if the server has processed the client's
usercmd for the frame in which the client predicted the value.
Got that?
