Added ability to setStereoElements - this was required due to clone() being shall on List. We need to be able to set a new array when have cloned a AtomContainer
Added unit tests for DoubleBond and AtomParity cloning

Reworked AtomContainer.clone() so it is clear what is going on. We now use a HashMap between the original and cloned atoms to avoid to a linear search each time the atom mapping is needed. This is also useful when we add StereoElement cloning (not yet implemented). We also store a bond mapping as well - we will need the bond mapping for double bond stereo chemistry. The stereo elements in the clone need to be set to an empty array on the clone so we don't remove elements from the original (cloning odditity). It was also clear we need to change the clone() method on Polymer which currently undoes all the cloning work we do in the AtomContainer. For all clone instances I added some code to correctly create HashMaps that won't need to resized. The default HashMap implementation works best at 0.75 capacity - we therefore need to do some simple arithmetic to ensure we don't get a resize. The implemented method is what is used in the Guava library.

Added a 'map' method on all IStereoElements. The map method allows a stereo element on one container/molecule to mapped to a stereo element on another. This mapping is achieved using two symbol tables, one for atoms and one for bonds. All methods are null safe and the mapping will not fail if any content in the stereo elements is null. The mapping simplifies the cloning of molecules/atom containers but could also be used when comparing isomorphic graphs.

Added unit tests for bugs 1270 (removalAllElements should remove stereo elements) and 1273 (double bond stereo chemistry constructor should throw an exception on wrong input). Added @cdk.bug tag for bug 1264 (stereo element cloning)

Resolved NoNotify fails on AtomParity. Error was due to subclassing of AtomParity. Also the assertEquals params were swapped as the assertion was the wrong way.
