REACT NATIVE REDUX FILE LOGGER

Introduction

This project exports a middleware that creates a csv log file in the android/ios file system. It has the following functionalities:

1. Gives the developer control over what actions need to be logged inside the csv file.
2. Can be plugged into any project with minimal setup.
3. Provides the name of the CSV file back to the project so that the user can use it to either send to the server or email or do anything with it.
4. Fault tolerant if any of the write calls to the file system fails.
