apfel

Create a Python-based task management application named 'TaskMaster' that leverages the 'apfel' package to enhance its functionality. TaskMaster should allow users to add tasks, mark them as completed, delete tasks, and list all tasks along with their status (completed or pending). Additionally, implement the following features:

1. **Search Functionality**: Allow users to search for specific tasks by keywords.
2. **Priority Levels**: Enable users to assign priority levels (low, medium, high) to tasks.
3. **Due Dates**: Tasks should have due dates which can be set by the user.
4. **Statistics**: Display statistics such as total number of tasks, number of completed tasks, and number of overdue tasks.
5. **User Interface**: Develop a simple command-line interface for interacting with the application.

**Utilization of 'apfel' Package**:
- Use 'apfel' functions to streamline the process of adding, modifying, and deleting tasks. For instance, utilize 'apfel' for functional operations like filtering tasks based on their status or priority level.
- Implement 'apfel' utilities to manage collections of tasks efficiently, ensuring the application remains performant even as the number of tasks grows.
- Leverage 'apfel' for any other utility that enhances the task management process, such as date manipulation or string formatting for better output presentation.

Your goal is to create a robust, user-friendly task management tool that showcases the capabilities of the 'apfel' package while providing practical value to the end-user.
