/**
* This interface is used to retrieve the current instance of the TimetableSnapshot. Any provider
* implementing this interface is responsible for thread-safe access to the latest valid
* instance of the {@code TimetableSnapshot}.
*
* Note that in the long run we don't necessarily want multiple snapshot providers. Ideally we'll just have one way of
* handling these concurrency concerns, so no need for an interface and multiple implementations. But in the short term,
* handling both GTFS-RT and SIRI has led to two different providers.
