Finite volume data

In the finite volume method, the data is stored separately throughout the cells. Therefore, we provide AbstractControlVolume and AbstractInterface structs for processing in-cell and edge information, which are used as arrays of structs (AoS) in numerical simulations. Considering one-dimensional physical space $x$, we provide the following control volume structs. The structs differs from the number of particle distribution functions.
