Summary of ChangesHello @tdavidcl, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request refines the ghost particle interaction mechanism within the SPH (Smoothed Particle Hydrodynamics) simulation. The core enhancement is the implementation of a symmetric interaction criterion, addressing a previous asymmetry in how interaction volumes were determined. This update is encapsulated within a new preprocessor directive, providing flexibility for testing and deployment of the improved model. Highlights

Code Review
The pull request modifies the BasicSPHGhostHandler::find_interfaces method to correct an asymmetric ghost interaction by expanding bounding boxes using the maximum of sender_h_max and receiv_h_max for intersection checks. This change is currently implemented under a NEW_GZ_INTERACT_CRIT preprocessor macro. Review comments suggest removing this macro and the old code path, as it's a bug fix, and also recommend refactoring to consistently use shammath::AABB for bounding box operations instead of mixing it with shammath::CoordRange to improve code clarity and consistency.
