🧪 Comprehensive Test Suite for Modular Qualitative Reasoning System
====================================================================

This test file provides comprehensive testing for the modular qualitative reasoning system
to ensure all modules integrate correctly and core functionality works as expected.

The test verifies that:
- All imports work correctly
- All mixin functionality is preserved  
- The modular system produces the same results as expected
- Factory functions create working QR systems
- No functionality has been lost in the modularization
- Security improvements are working

Test Categories:
1. Basic initialization and imports
2. Adding quantities, states, and processes
3. Constraint evaluation functionality
4. Simulation engine
5. Individual module functionality
6. Module integration
7. Factory functions  
8. Analysis and visualization capabilities
