//
// Class CellParticleCachingPolicy
//
//   The Cell caching layout ensures that each node has all ghost particles
//   for each external particle that is inside a neighboring cell.
//
//   Please note: for the time being this class is *not* used! But since it
//   might be used in future projects, we keep this file.
