Adds Calcite library. Implements:
- Select style
- Toggle style for normalization checkbox
- Animations for two primary widgets
Also updates the boundary outline layers to a new, hi-res version for both states and the USA.
I attempted to handle the select and option nodes width by adding select2, but it looks like we've got a jQuery conflict happening with it. I've commented this out for now.
I also tried to add the DOM nodes and required Calcite classes to add a loader, but I'm pretty sure this will require an event listener to remove the is-active class. It would be nice if the div was full page as well, with the loader bars in the center. I'll look into that for the next PR.
