Initialize the plugin on your menu element

<header id="main-header">

    <ul>
      <li><a href="#features">Features</a></li>
      <li><a href="#usage">Usage</a></li>

<a href="#anything" data-target="selector">Anything</a>

var elm = document.querySelector('#main-header');
var ms = new MenuSpy(elm);

The MenuSpy() constructor accepts two arguments: the container element and an options object.
