React component to listen to keydown and keyup keyboard events, defining and dispatching keyboard shortcuts. Uses a fork of hotkeys.js for keydown detection of special characters. You give it a keymap of shortcuts & it bind it to the mousetrap singleton. The, it'll unbind it when the component unmounts.
