Journal Pagination

As a journal reader, I would like to view a single journal entry at a time, so that I am not overwhelmed by information when I list journal entries.

NOTE: this feature allows users to scroll through journal entries with their arrow keys.

Then they should be presented with the first journal entry

Given the user is viewing a single journal entry
When they push the down arrow button
Then they should be presented with the next journal entry

Given the user is viewing a single journal entry
When they push the up arrow button
Then they should be presented with the previous journal entry

Given the user is viewing the first journal entry
When they push the up arrow button
Then they should be presented with the last journal entry
