Including the beam library in the SMILES module.
Conversion of the CDK object model to Beam.
Conversion from Beam to CDK objects.
Iodine only belongs to the aliphatic and not the aromatic subset - it can not be lower case and this test does not work as intended. A correct example is to have an aliphatic carbon and an aromatic oxygen which make the symbol of Cobalt (non organic subset atom).
Removing redundant bracket. Generally such an error indicates something deeper is wrong. This test was checking hydrogen counts though so we can safely remove it.
