Create an empty timetable cache that uses the specified `loader` to load timetables on demand and has the specified `timeout` interval indicating the length of time that timetables remain valid for subsequent retrieval from the cache after they have been loaded. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `bsls::TimeInterval() <= timeout <= bsls::TimeInterval(INT_MAX, 0)`, and `loader` remains valid throughout the lifetime of this cache. Note that a `timeout` value of 0 indicates that a timetable will be loaded into the cache by _each_ (successful) call to the `getTimetable` method.
