general function to generate grids grid_type= LGL, LG, or FGH mapping_type= linear or algebraic(reciprocal) This function does 1) set parameters of N and grid_type 2) allocate memory for r, rp, D1, D2, and so on 2) make computational grids 3) make real grids by means of a mapping function 4) construct D1 and D2
