This node cleans unecessary bonds:

• Single bonds - only retained then they are between two aromatic atoms
• Aromatic bonds - all removed

This is to comply with the suggestion in OpenSMILES that these bond types are implicit, and so the only need for them is for an explicit single bond between two aromatic atoms
