Draggable Comments

[pletcher]

In response to some of the feedback from the user survey, I've been working on a draggable interaction that allows comments to be moved around and expanded anywhere on the screen, simulating a sort of "desk-like" interface with different "books" opened to different pages. (See the CommentGrid story for the current implementation.)

But this interaction is difficult, and there are still many things to do to fine-tune it.

• Comments are draggable only by a "handle" (top bar)
• Comments are user-resizable (like desktop windows)
• Comments can be dragged outside of the grid and "pinned" so that they are visible even when the grid container is closed
• Comments can be reset to their original positions (remove neodrag and neodrag-dragged classes and reset neodrag styles)
