Module supercell_mod

Perform supercell expansion for a structure.

New lattice parameters are multiplied and fractional coordinates
divided by corresponding multiplier.  New atoms are grouped with
their source in the original cell.

S   -- an instance of Structure from diffpy.Structure.
mno -- sequence of 3 integers for cell multipliers along
       the a, b and c axes.

Return a new expanded structure instance.
Raise TypeError when S is not Structure instance.
Raise ValueError for invalid mno argument.
