WhatsApp ChatBot Engine
Core template engine
The core purpose of the library is to provide a template-driven WhatsApp ChatBot Engine
From now on, we will focus on the engine part of the library

The previous section setup still applies.
Engine Setup
The previous section touches on using pywce as just another WhatsApp Client Library. Much of the setup remains the same, what differs is how the webhook payload is processed, lets dive deep.
Templates
Templates are the engine's first-class citizens. They are defined in .yaml files and you can store them in any location you prefer
