 In the code, `rsq` represents the distance between atoms `i,j`. It is saved in squared form to avoid computing an expensive `sqrt`.
-- If `rsq` is larger than `cut_bothsq`, then, no computation is required because there is no short-range interaction between the two atoms. In that case, the inner loop iteration stops here (*do nothing*).
-- If `rsq` is smaller than `tabinnersq`, then `forcecoul` is computed using a *fast* table method. If not, it  is computed using a *slow* method with calls to `sqrt` and `exp` functions.
-- If `rsq` is bigger than `cut_lj_innersq`, then `forcelj` needs a few additional computations.
