🔧 Development Guide

Creating New Calculators

1. Create a new calculator file in the calculators/ directory

2. Inherit from the BaseCalculator class

3. Implement required methods: get_info(), validate_parameters(), calculate()

4. Register using the @register_calculator decorator

5. Add import to calculators/__init__.py
