	<!-- 	This file supplies penalty scores for different 
	  		atom types in bond type perception accoring to 
	 								 	
	 				Wang, J., Wang, W., Kollman P. A.; Case, D. A. "Automatic atom type and 
	 				bond type perception in molecular mechanical calculations". Journal of 
	 				Molecular Graphics and Modelling , 25, 2006, 247260	

				A penalty score of 0 means that the corresponding valence is optimal.
				Note that the first matching entry is taken as the final atom type.

				Note that in the SMARTS strings we use atomic numbers rather than symbols (e.g. #8 instead of O).
				The reason is that wrongly assigned aromatic bonds in the input would lead to failure to identify the
				right rule!
