Implement Tutorial 2

[mandolyte]

Suggest: building on the first tutorial, implement a translation help in each tab. For example, if there are three tabs, then for a given book (see below), then have the following:

• a tab containing translation notes
• a tab containing translation word list
• a tab containing translation questions
  (note: all of these are TSV formats... maybe some variety should be considered)

Note on Book Input:
In the figma mockups here, an "add" button is shown. Perhaps such a button could be used to select a book?
