Scratch area / pane / file

[gordonwoodhull]

It'd be nice to have a scratch area on the side where one can keep snippets of code to paste into the active section. Even better, assign a key combo to copy text and execute it in the notebook proper.

This will require some changes to the layout.

It could also be used for modifying the (not yet used) notebook CSS, which will help e.g. with dc.js. We may need some sort of picker or tabs to decide what "extra file" to edit in the scratch area.

This and #21 are blocked on just requiring some design / layout decision.

I suggest that we don't try anything too general but just have two possible layouts:

1. with one column, as now
2. with two columns/panes, getting rid of most of the margin, and putting the auxiliary/scratch file or help in the right column/pane. In addition, the second pane could have some tabs or other selectors to go between extra files and help. And have a close button to return to one-pane mode.

I hold this would not be too overwhelming / geeky-looking, but would allow just a little spread of attention. IMO we don't want to go all jsFiddle with this, but we need a little bit area to work with.
