title: MDCSnackbarFoundation Class usage
body: <p>How do I use MDCSnackbarFoundation ? with MDCSnackbar</p>
  
  <p>This documentation is not clear enough to get an idea.
  <a href="https://github.com/material-components/material-components-web/tree/master/packages/mdc-snackbar#using-the-foundation-class" rel="noreferrer">https://github.com/material-components/material-components-web/tree/master/packages/mdc-snackbar#using-the-foundation-class</a></p>
  
  <p>This is my code and I need to bind MDCSnackbarFoundation for it. </p>
  
  <p><code>logger = new MDCSnackbar($selector[0]);</code></p>
  
  <p>Thanks</p>
