 This forks classic-level's C++ binding code around LevelDB 1.20. Differences from classic-level:
 
-* Uses TypeScript from ground-up
-* Supports Snapshot-Isolation based transactions via `DBTransaction`
-* API supports "key paths" which can be used to manipulate "levels" of nested keys
-* Value encryption (key-encryption is not supported yet) - requires additional work with block-encryption
-* Uses RocksDB
