Directory Structure

The working directory is assumed to be the directory of the application for which the Custom Watcher is implemented.

.qr-detector-app
│   app.js
│   index.html    
│   package.json
│   README.md
│   vendor.js
│
└─── watchers
        └─── qr-code-detector
                    └─── qr-code-detector.py

IMPORTANT: Note that the directory in which the .py file is placed, should be named exactly as the .py file.
