Reusable modal component (#50)
* README proposal. * First pass at implementation of proposal on Footer and Header. Footer could use some work. * Cleanup, and readme additions * First pass at basic modal * Modal open / close * Modal close on esc key. * Freeze body scrolling when modal is open. * Use the index bestowed upon me. * No close on shade click * Only render children if modal is open. Also, dont show cursor on shade * Use flexbox for simpler content height / scroll behavior. * type modal, fix body scroll when mounted opened * Modal width is sized by content, not hard coded sizes. * Remove size from flow prop types.
