 #### 3D Bravais Lattices
 All 3D Bravais lattices created from the SimpleCrystal's API and visualized in [OVITO](https://ovito.org/). The radius of the atoms is chosen arbitrarily in OVITO.
 The full list of implemented functions can be found [here](https://github.com/ejmeitz/SimpleCrystals.jl/blob/main/src/bravais/3D_bravais.jl).

 Both methods yield the same structure with periodic boundary conditions, but the first function uses a conventional cell so the result is much easier to see and create a simulation box for. Whenever possible use a conventional cell (simple cubic lattice). Note that to use both of these functions the lattice parameter a is the distance between Na atoms (or Cl atoms) not the Na-Cl distance as the basis places the atoms at the proper 0.5*a spacing.
