athena-ptc-emitter

Create a simple Python application named 'EventLogger' that leverages the 'athena-ptc-emitter' package to demonstrate event handling within a sandboxed environment. This application will serve as a basic logger tool, where various events (such as file operations, user actions, and system notifications) can be emitted and handled through custom listeners.

### Application Overview:
- **Event Emitter**: Utilize 'athena-ptc-emitter' to create an event emitter instance that will emit different types of events.
- **Event Listeners**: Implement multiple listeners that respond to specific types of events. For example, one listener could log file operations to a text file, while another might send an email notification for critical system alerts.
- **User Interface**: Develop a simple command-line interface (CLI) for users to trigger events manually or through predefined scripts.
- **Configuration**: Allow users to configure which events are monitored and how they should be handled via a configuration file.

### Key Features:
1. **Dynamic Event Handling**: Users should be able to define new events and their corresponding handlers at runtime without restarting the application.
2. **Logging Mechanism**: Events and their timestamps should be logged into a structured format (e.g., JSON) for easy analysis.
3. **Extensibility**: The application should support plugins or extensions that can add more sophisticated event handling capabilities, such as integrating with external APIs for real-time data processing.
4. **Security**: Ensure that only authorized events are processed to prevent misuse within the sandboxed environment.
5. **Documentation**: Provide comprehensive documentation on how to use the application, including examples of common event types and handler implementations.

### Utilization of 'athena-ptc-emitter':
- Use 'athena-ptc-emitter' to instantiate an event emitter object.
- Define event names and attach listener functions to these events using the emitter's API.
- Emit events based on user input or predefined conditions.
- Handle errors gracefully when emitting or listening to events to maintain application stability.

### Example Workflow:
1. Start the application from the CLI.
2. Configure initial settings through a provided configuration file.
3. Manually trigger an event (e.g., 'file_created') from the CLI.
4. Observe the event being logged and any associated actions (e.g., logging to a file).
5. Modify the configuration to add a new event type and its handler.
6. Restart the application to apply changes and test the new functionality.

This project aims to showcase the flexibility and power of event-driven architecture within a constrained environment, leveraging the 'athena-ptc-emitter' package for efficient event management.
