 Chemistry::OpenSMILES provides support for SMILES chemical identifiers
 conforming to OpenSMILES v1.0 specification.
 .
 Chemistry::OpenSMILES::Parser reads in SMILES strings and returns them parsed
 to arrays of Graph::Undirected objects. Each atom is represented by a hash.
 .
 Chemistry::OpenSMILES::Writer performs the inverse operation. Generated SMILES
 strings are by no means optimal.
