ParislibMap od Aurelien David

When clicking "Choisir une librairie" on a parislibrairies.fr page, you will have options to:

- add the book to the map to see where it is available
- previously added books show up too (you can just display the map without adding the current book with the "Afficher la carte" button)
- you can remove books from the list with the trash icon
- the Intersection markers show where all the books are available
- you can specify which books are counted in the intersection with the rings icon on the right
