If the OETautomerOptions.GetSaveStereo method returns true, this flag is irrelevant.
The default value is OERacemicType.LocalSampled.
This option indicates that no racemic type will be set.
This option indicates that individual tautomers that have double bonds to tetrahedral stereocenters will have the stereo removed.
This option indicates that if an atom which are tetrahedral stereocenters has a double bonds in any of the tautomers returned by the function, then those tetrahedral stereocenters will have the stereo removed in ALL of the returned tautomers.
