 - The JSDoc is now much more exhaustive.
 - An auto-generated JSDoc file is generated: [API.md](./API.md).
 - Added `Datastore#dropDatabaseAsync` and its callback equivalent.
-- The Error given when there the `Datastore#corruptAlertThreshold` is reached now has three properties: `dataLength` which is the amount of lines in the database file (excluding empty lines), `corruptItems` which is the amount of corrupted lines, `corruptionRate` which the rate of corruption between 0 and 1.

 ### Changed
 - The `corruptionAlertThreshold` now doesn't take into account empty lines, and the error message is slightly changed.

     - `Executor#buffer` & `Executor#queue` do not have the same signatures as before;
