title: Highlight certain days for Angular Material Datepicker (>ng2)
body: <p>Is it somehow possible to highlight certain days / months (when in year view) using the <strong><a href="https://material.angular.io/components/datepicker/overview" rel="nofollow noreferrer">Angular Material Datepicker?</a></strong> <br />
  Like the displayed dates should be tested against a function in the component the datepicker is in and if that function returns true, then a CSS class should be added. <br />
  So basically <strong>something like <code>ngClass</code> for the displayed days / months</strong> (when in year view).</p>
