🌟 Summary

Introducing automatic code formatting for Ultralytics repositories 🖌️✨

📊 Key Changes

• Added a GitHub Actions workflow file named format.yml
• Automated code and documentation formatting on pushes and pull requests to main and master branches
• Updated importcsvNeutronFile.m to clear temporary variables with a small tweak in variable naming

🎯 Purpose & Impact

• Consistency: Ensures a consistent code style across the project, which simplifies reading and maintaining code. 📏
• Efficiency: Saves time for contributors by automating formatting, allowing them to focus on code logic and features. ⏱️
• Quality Control: Reduces the chances of human error and improves overall code quality. 🛠️
• Small adjustment in importcsvNeutronFile.m could be a bug fix or typo correction. (Note that it might be a mistake since 'ans' seems to be a valid Matlab temporary variable whereas 'and' is a logical operator.)

The impact is an increase in productivity for developers and a more streamlined contribution process for potential future updates or changes to the Ultralytics codebase. Users should experience the benefits indirectly through improved software robustness and consistency.
