typestub-node-lmdb

Typescript wrapper around node-lmdb, with some improvement.

Basically same as node-lmdb, except:

• beginTxn() is exposed only after the env is opened
• extended txn to include clear, getObject, and putObject methods

| additional method | explanation | | ----------------- | ------------------------------------------------------------ | | clear | try to delete, will not throw error if the key doesn't exist | | getObject | wrap around getString with JSON.stringify* | | putObject | wrap around putString with JSON.parse* |

*: exception raised from JSON.stringify/parse is not handled
