✨ Include SMILES strings for all molecules.

[astrogewgaw]

Need to find a way to include SMILES strings for each molecule. This will unlock a lot of additional functionality, like:

• Generating images of molecular structures (and images).
• Calculation of basic properties using other packages.
• Interfacing with other packages or databases

Need to look into whether this can be done automatically, using an existing package or database. I have my doubts, mostly because I don't think that a molecule's name/formula maps uniquely to a SMILES string.
