DIInjector

Create a fully functional command-line utility named 'ServiceManager' that leverages the 'DIInjector' package to manage and interact with various services. This utility will allow users to register, start, stop, and query different services dynamically. Each service will represent a distinct functionality, such as logging, data processing, or file management. Here’s a detailed breakdown of the project requirements:

1. **Project Setup**: Initialize a new Python project with all necessary dependencies installed, including the 'DIInjector' package.
2. **Service Definition**: Define multiple services using classes. Each service should implement a common interface that includes methods like `start()`, `stop()`, and `status()`.
3. **Dependency Injection**: Use the 'DIInjector' package to inject dependencies into your services where needed. For example, a logging service might need an instance of a file handler or a database connection.
4. **Service Registry**: Implement a registry mechanism to keep track of registered services. Users should be able to add new services at runtime through the command line.
5. **Command Line Interface**: Develop a CLI that allows users to interact with the ServiceManager. Commands should include registering a new service, starting/stopping services, checking the status of all services, and listing all registered services.
6. **Dynamic Loading**: Enable the system to load services from external modules or files based on user input.
7. **Error Handling**: Ensure robust error handling for scenarios such as invalid commands, missing dependencies, or failed service operations.
8. **Documentation**: Provide comprehensive documentation explaining how to use the CLI, how to extend the system with new services, and how the 'DIInjector' package is utilized within the project.

This project aims to demonstrate the power of dependency injection in managing complex applications while showcasing the capabilities of the 'DIInjector' package.
