- * simple, and a bit slow on big documents (Its O(N). However, it requires no
- * changes to the DOM and no heavy libraries like ace. It works for any kind of

- *
- * You probably want to use this binding for small fields on forms and such.

- *
- * This function should be called every time the text element is changed.
- * Because changes are always localised, the diffing is quite easy. We simply
- * scan in from the start and scan in from the end to isolate the edited range,
- * then delete everything that was removed & add everything that was added.
- * This wouldn't work for complex changes, but this function should be called
- * on keystroke - so the edits will mostly just be single character changes.
- * Sometimes they'll paste text over other text, but even then the diff
- * generated by this algorithm is correct.
- *
- * This algorithm is O(N). I suspect you could speed it up somehow using regular expressions.
