Allow users to choose between cylindrical (R,phi,z) and toroidal (rho,theta,phi) spatial grids and (ppara,pperp) and (energy,pitch) momentum space basis when using AFSI. Toroidal grid is very useful for stellarators while (energy,pitch) is more convenient when calculating thermal fusion products. Using more suitable grid increases accuracy and reduces memory consumption.
