Welcome to the third lesson of our "Applying Design Patterns to Real-World Problems in Rust" course! 🎉 In this lesson, we'll explore two powerful design patterns: the Command pattern and the Decorator pattern. These patterns will empower you to design a robust and flexible smart home automation and lighting control system in Rust. Let's embark on this journey to create a system that's as adaptable as it is efficient! 🚀

In this lesson, we'll dive deep into implementing the Command and Decorator patterns. Here's what we'll cover:

1. Define Smart Home Appliances: Create a simple Appliance struct with methods to control devices.
2. Implement the Command Pattern: Develop a Command trait, concrete command structs (TurnOnCommand, TurnOffCommand), and an AutomationController invoker to manage and execute commands.
3. Implement the Light Trait and Decorators: Define a Light trait and create decorators (BasicLight, DimmableLight, ColorChangingLight) to enhance light functionality dynamically.
