Rokas slider

[RokasEl]

Implemented support for specifying multiple smiles in the smiles_col argument for molplotly.add_molecules:

• When a single str argument is passed to smiles_col, the function behaves as before.
• When a list is passed, a slider is created under the plot, which allows the user to decide which column to use to render molecules.

Also changed the ports in the example.ipynb to start from 8700 and go up. On my system 8000 and 8001 were reserverd already.

Maybe use a drop-down menu instead? That way you can choose multiple options at once and it should be possible to show multiple images in the same hoverbox (though it might not be a good idea :P)

See here, should be a small change to your addition https://dash.plotly.com/dash-core-components/dropdown
