As a new iOS user, I'd love to see some "less than apple approved" things going on the iOS platform. Can we get a list going?

Describe the bug
When exporting annotation with Flashcard, the JSON line is undefined

    },
    undefined,
    {

To Reproduce
Steps to reproduce the behavior:

1. Annotate a line of text
2. Add a Flashcard with data on back and front
3. Export annotation as JSON
4. Search "undefined" you should get to that badly exported entry

Expected behavior

Fla

These functions have very similar logic, and are largely duplicates of each other. DRY them up.

Summary of Requirements

• Create pre-refactor unit tests for Mode2Up.flipLeftToRight and Mode2Up.flipRightToLeft
• Mode2Up.flipLeftToRight and Mode2Up.flipRightToLeft should still exist, but call a helper function which takes more parameters and reduces code duplication
• [ ]

Please report any duplicate entries here. Don't open separate issue for every duplicate.
