-// SyncSessionContext encapsulates the contextual information and engine
-// components specific to a SyncSession. A context is accessible via
-// a SyncSession so that session SyncerCommands and parts of the engine have
-// a convenient way to access other parts. In this way it can be thought of as
-// the surrounding environment for the SyncSession. The components of this
-// environment are either valid or not valid for the entire context lifetime,
-// or they are valid for explicitly scoped periods of time by using Scoped
-// installation utilities found below. This means that the context assumes no
-// ownership whatsoever of any object that was not created by the context
-// itself.
-//
-// It can only be used from the SyncerThread.
