Basic example of the navigation component

```jsx
const Router = require('react-router').MemoryRouter;
const IconButton = require("@material-ui/core/IconButton").default;
const NotificationsNoneIcon = require("@material-ui/icons/NotificationsNone").default;
const ViewComfyIcon = require("@material-ui/icons/ViewComfy").default;
const AccountCircleIcon = require("@material-ui/icons/AccountCircle").default;
<Router>
  <OpNav
      linkSrc="www.google.com"
      position="sticky"
    >
      <div style={{flexGrow: 1}} />
      <IconButton>
        <NotificationsNoneIcon />
      </IconButton>
      <IconButton>
        <ViewComfyIcon /> 
      </IconButton>
      <IconButton>
        <AccountCircleIcon />
      </IconButton>
    </OpNav>
</Router>
```
