- Using icons in the feedback headers
- fix for line number positioning when single column
Feedback Flipper code now works
- drawFeedbackFlipper is called from redrawFeedback
- draws after the second piece of feedback is returned (2 submissions)
- highlights and unhighlights previous next arrows as they become relevant
- reports total number of attempts and the one currently navigated to
- introduces a private property called responseIndex_
- styles all these headers in brix.css
Switched from i tag to span tag for icons
Moving the "suggested answer(s)" into the left column as designed.
Note that this implementation does not return the suggested answers in the case of a correct answer, which it should.  Student should always see this data if a problem is "complete".
Reclassing div with code examples so it doesn't get the flipper drawn into it. Note that this piece should not redraw once drawn.
Cleanup correct suggested code in the left column under the text entry field.
- made it only appear once even when user flips back and forth between feedback
- styled it with line numbers and zebra striped rows using ol and lots of styling.
Added a comment with a suggestion for how to do multiple suggested correct code entries, since we don't really deal with the array right now.
