Fix design patterns according to custom rules
This code change simplifies a network server project by removing an experimental comparison between two programming approaches. Originally, the project demonstrated both "good" structured programming and "bad" goto-based programming to show the difference in code quality. The changes remove the goto version entirely, keeping only the clean, well-structured implementation.
The main updates include:
- Removing all goto-based code and references to it as a "research project"
- Simplifying the project to focus solely on demonstrating good programming practices
- Cleaning up comments and documentation to reflect the single implementation
- Removing command-line options that let users choose between the two approaches
- Streamlining the client code by replacing a goto statement with proper structured control flow
The end result is a cleaner, more focused codebase that serves as a good example of how to write a network server using proper programming techniques, without the distraction of showing bad practices alongside the good ones.
