Detailed Description

template<typename ScalarType>
class terra::communication::shell::FVGhostLayerBuffers< ScalarType >

Pre-allocated send/recv buffers and sorted face-pair lists for FV ghost layer comm.

Construct once per operator (or wherever ghost layer updates are needed), then pass to update_fv_ghost_layers on every call. No heap allocation happens after construction.
