export smiles

Thanks for your contribution ！

I want to export smiles , but it's always export empty. I try to export 'cml' and it works.

const Kekule = require('kekule')
const mol = new Kekule.Molecule()
const smiles = Kekule.IO.saveFormatData(mol, 'smi')
console.log('SMILES: ', smiles)

let molecule = composer.getChemObj(); smiles_data = Kekule.IO.saveFormatData(molecule, 'smi'); console.log(smiles_data)

let molecule = composer.getChemObj(); smiles_data = Kekule.IO.saveFormatData(molecule, 'smi'); console.log(smiles_data)

thanks for your answer, it works!
