We need an API that allows to add the data directly in the database.

The unicity is based on idCode and source. If it exists and there is a new post we should replace the existing data and all the corresponding hose codes.

idCode and coordinates are obtained using:

https://cheminfo.github.io/openchemlib-js/classes/Molecule.html#getIDCodeAndCoordinates

We need 2 fields in the molecule database:

• idCode - unique code that allows to identify a molecule
• coordinates - coordinates of the atoms allowing to draw the molecule the way to chemist likes to see it (or have 3D coordinates)
