appfx-di

Create a simple task management application using Python, which leverages the 'appfx-di' package for dependency injection. This application will allow users to create tasks, assign them to different categories, mark tasks as completed, and delete tasks. The goal of this project is to demonstrate how 'appfx-di' simplifies the process of managing dependencies within complex applications, making it easier to manage objects and their relationships without directly handling dependencies yourself.

### Features:
- **Task Creation:** Users can add new tasks with a title, description, and category.
- **Category Management:** Users can create, modify, and delete categories to organize tasks.
- **Task Completion:** Users can mark tasks as completed.
- **Task Deletion:** Users can remove tasks from the system.
- **Dependency Injection:** Utilize 'appfx-di' to inject dependencies such as data access layers, service providers, and logging into your application components.

### Steps:
1. **Setup Project Structure:** Initialize your Python environment and install necessary packages including 'appfx-di'.
2. **Define Application Components:** Create classes for tasks, categories, and services that interact with these entities.
3. **Configure 'appfx-di':** Use 'appfx-di' to define bindings between interfaces and implementations, ensuring that services and repositories are properly injected into your components.
4. **Implement Core Functionality:** Write functions to handle CRUD operations on tasks and categories, utilizing the dependency-injected services.
5. **Testing:** Ensure all functionalities work as expected by testing each feature thoroughly.
6. **Deployment:** Prepare your application for deployment, considering packaging and possibly setting up a web interface or CLI for user interaction.

By following these steps and focusing on the integration of 'appfx-di', you'll not only build a functional task manager but also gain valuable experience in dependency injection and Python application development.
