Tablist initial

Looks good. Nice and responsive. Some general comments:
 - Clean up SCSS
   - No need for ```& > nav``` just a simple ```> nav``` will work. The ```&``` operator is more for pseudo-selectors. Simply nesting the selectors achieves what is required.
   - Maybe some initial vertical spacing between tab panels in stacked (mobile) rendering.
   - Maybe some padding on tab panels always. Otherwise this will encourage usage to leverage an additional wrapper element for spacing (bloating the DOM), or will require careful application of margin/padding to all contained elements.

 - Coding standards
   - Watch spacing around operators and function expressions.
   - Try to manually hoist ```var``` declarations to the top of the functional scope as much as possible.

 - Incorporate ability to load CSS dynamically if not already loaded.

 - If we're going for ARIA accessibility, maybe ...
   - Consider using ```aria-expanded``` (or ```aria-hidden```) attribute on ```tabpanel```s to indicate visibility.
   - Consider using ```aria-selected``` attribute on ```tab```s to indicate selectedness.

 - Allow for tablist to enhance pre-existing markup. I.E. scan ```this.el``` for existing content (```nav```, ```.tablist-panel``` elements) and enhance what is already there. Have you considered otherwise how (possibly) extraneous content might render inside the element used for the tab list?
