The seventh sprint is themed around the learnings on:

• Continuing Tinkr Shelf work.
• Researching into the type of DB to use given book storage and usage data storage.
• Creating a DB schema for the usage data if necessary if Firebase doesn't handle offline storage well.
• Researching how to "package" Tinkr Book files for storage on a server in a compressed format and writing a function to unpack that format.
