Full page pileup

[danvk]

Fixes #718

This also fixes the "mousewheel in the pileup track scrolls the variant list" issue. Mousewheeling elsewhere in the variant inspector still does this, but the situation is at least improved!

The full-page pileup view includes a one-row VCFTable. In setting this up, I found a few unused props which I removed.

This uses CSS flexbox to size the tracks in the pileup view. This works so well that I might make it the default in pileup.css.

LGTM, three minor issues:

1. http://d.pr/i/1edTw
2. http://d.pr/i/131eh
3. Some way to get rid of the scrollbar on the main page would be ideal; can't we just not render the main VCFTable if pileup is open?

Good suggestion about not rendering the VCFTable when the pileup viewer is open. I reworked ExaminePage.js to show only the pileup or the rest of the examine page, never both. This fixes all three of your minor issues. It also lets me kill the mousewheel hack.

Lemme know what you think.

Awesome, LGTM!
