Interface to 'LMDB'
Key-value store, implemented as a wrapper around 'LMDB'; the "lightning memory-mapped database" <https://www.symas.com/lmdb>. 'LMDB' is a transactional key value store that uses a memory map for efficient access. This package wraps the entire 'LMDB' interface (except duplicated keys), and provides objects for transactions and cursors.
