Calibre server as a digital library/ebook management application on FreedomBox

The latest version of Calibre (3.19) has a server component with the following features:

1. Ability to switch between multiple libraries
2. Browse ebooks in a Calibre library
3. Add or remove ebooks from the library
4. Read ebooks in the browser or download to read offline.

Calibre is already quite popular as a desktop application. Users already using Calibre might have their ebook collections scattered across multiple desktop Calibre applications. Running a Calibre instance on a FreedomBox allows access from anywhere.

It also allows easy sharing of ebooks and other documents in a community. For example, in a community deployment like in a village or a school, Calibre running on a FreedomBox might hold textbooks for students.
