This module contains the database versioning abstractions.
Like LevelDB, RainDB is represented by a set of versions and this set of version is maintained by
the [`VersionSet`] struct. Explicitly the most up to date version is tracked as the "current"
version and older versions may be kept around to provide a consistent view to live iterators.
Each [`Version`] keeps track of a set of table files per level.
# Concurrency
[`VersionSet`] and [`Version`] require external synchronization e.g. a mutex.
[`VersionSet`]: version_set::VersionSet
[`Version`]: version::Version
