This constant indicates no options.
This constant indicates that any existing bonds in the input molecule can be used. Missing bonds will still be perceived. Without this option, if any alternate location codes are found in the input mol, any bonds found will be ignored.
Since the basic bond perception mechanism will usually fail on a molecule that contains
alternative conformation atoms, this option should only be used when special care
has been taken with the input molecule (for example, if the molecule comes from
