Manual radial matrix elements EDAC

The program will take the value of the initial angular momentum l0 (e.g., 0 for s, 1 for p, etc.) as that of the core, and the radial matrix elements will have a magnitude Rl0+1 and Rl0-1 for the l0+1 and l0-1 channels (in a.u.), and their phases will be δl0+1 and δl0-1 (in radians), respectively. These parameters are taking from the user input.
