Ghost data used on the subcell grid for reconstruction
This class holds both the local ghost data on the local subcell mesh for a given direction, as well as the neighbor's ghost data (on the neighbor's mesh) in that same direction. This class is similar to evolution::dg::MortarData in the sense that it holds both local and neighbor data in a direction. However, it differs because the local ghost data is not used in our own calculation when reconstructing the solution at the face between the elements. This is because we already have our own data on our own FD grid. Only the neighbor ghost data is used to reconstruct the solution on the face.
With Charm++ messages, storing the local ghost data is necessary because it must live somewhere so we can send a pointer to our neighbor.
