Replace hard-coded engine instantiation with factory pattern
to enable dependency injection and improve testability.
Changes:
- IEngineFactory: Interface for creating engines
- EngineFactory: Default implementation using AdvancedFitEngine
- MultiBinEngine: Now accepts IEngineFactory via constructor
This eliminates the hard-coded dependency on AdvancedFitEngine
and allows for easy swapping of engine implementations through
configuration or dependency injection.
Benefits:
- Dependency inversion principle satisfied
- Engines can be mocked in tests
- Engine selection can be configured externally
- Single responsibility for engine creation
