Stocks IA using YCharts

Need help getting the triggers sorted out, but I think the UI is close (at least until we get the charts).

The overriding difficulty is because the spice css is included earlier in the page than the core css, so you need extra specificity (more than one class) like this in order to override the defaults.  This is actually preferred though to prevent spices from overriding core css.  

`.stocks__header.zci__header` or `.zci--stocks  .stocks__header` would read better and work just as well I think.

I think the problem you ran into with `.zci__header__sub` though is that it's meant to be nested instead of the `.zci__header` element - what you wanted there was something like `.zci__header--sub` instead that didn't have the left padding etc, but that doesn't exist yet.
