Reduce a property from all ghost particles to the corresponding master particle.
- This kernel does not broadcast the reduced property to all ghost particles. Use BroadcastProperty or SyncNextNeighbors for that.
- The property which will be reduced can be selected by the Notification template (see ForceTorqueNotification). void reduce(data::Particle&& p, const Notification::Parameters& objparam) will be called to reduce the all incoming properties.
- the property is up to date on all ghost particles
- the property at all ghost particles stays unchanged
- the property at the master particle is the reduced one
