- Removes unnecessary uses of the native `path` module for the browser and React-Native version by replacing the internal `Persistance.ensureDirectoryExistsAsync` static method with `Persistance.ensureParentDirectoryExistsAsync` so that any `path` functions are used only in Node.js where it is necessary, as it is not necessary for the browser and React-Native [#51](https://github.com/seald/nedb/pull/51).
- Explicit return/callback type for update based on options [#44](https://github.com/seald/nedb/pull/44), thanks [RobMayer](https://github.com/RobMayer).
