aizp-protocol

Create a fully-functional mini-app called 'ProtocolPal' using the Python package 'aizp-protocol'. ProtocolPal will serve as a user-friendly interface for sending and receiving messages over a custom protocol based on 'aizp-protocol'. This app will allow users to connect to a server, send text messages, receive text messages, and manage their connections efficiently.

Step-by-step guide:
1. Set up the basic structure of the app including necessary imports from 'aizp-protocol' and other required packages.
2. Implement a function to establish a connection with a specified server using 'aizp-protocol'.
3. Develop a feature to send text messages to the server. Ensure error handling is implemented for failed transmissions.
4. Create a method to listen for incoming messages from the server. Display these messages in a clean, readable format.
5. Include functionality to disconnect gracefully from the server when the user decides to exit.
6. Add a simple command-line interface (CLI) where users can input commands like 'connect', 'send', 'receive', and 'disconnect'.
7. Enhance the CLI with a menu system for better user interaction.
8. Test the app thoroughly under various conditions to ensure reliability.

Suggested Features:
- Support for multiple simultaneous connections.
- Logging of all sent and received messages for auditing purposes.
- Ability to send binary data alongside text messages.
- User authentication before allowing access to the messaging service.
- A help command within the CLI to guide new users.

How 'aizp-protocol' is Utilized:
- For establishing secure and reliable connections between the client and server.
- For encoding and decoding messages according to the defined protocol specifications.
- For managing the lifecycle of the communication session, including initial handshake, message exchange, and disconnection.
