	* Version 1.2 - This version writes two files with containing the geometries with the smallest RMSD.
	                example:
	                ./saics struct1.xyz struct2.xyz will write the new files:
	                centered_struct1.xyz  containing the first structure centered in the center of mass
	                best_rmsd_struct2.xyz containing the best superposition between the two structures
			These structures can then be used to create figures or just to visualize the results.
