FaaS v0.4.0

Major improvements to processing pipeline, options available, REST API, and user experience, including:

• Better deployment with Docker and Gunicorn
• A decent web interface
• Pipeline almost exclusively in Python (with minor subprocess calls)
• A lot more options to customize the filling
• Minimal error handling

Thanks to Bruno Ribeiro for important contributions.
