Stereo elements are handled via STEREO_ELEMENTS_PROPERTY instead of CDK iterator
Refactoring to fix small typo
Added some comments. Refactoring: checkStereoElementsProperty() --> checkStereoElementsStoredAsProperty()
Un-commented function cloneAndCheckStereo() - it is used in ambit-tautomer module
One additional comment
Added comment for using CDK stereo elements iterator
Refactoring: setSteroElementsAsProperties() --> setSteroElementsAsAtomAndBondProperties()
Stereo elements are handled via molecule property instead of immutable CDK stereoElements() list
