title: Set footer colour in xml
body: <p>I am using the ViewPageIndicator library in my app. I know I can change the footer colour by using something like .setFooterColor(Color.Red) in my code. My question was if I can set this in xml instead as I would like to to all the styling in xml.</p>
  
  <p>Below is the xml code</p>
  
  <pre><code>&lt;com.viewpagerindicator.TitlePageIndicator
      android:id="@+id/indicator"
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"     
      /&gt;
  </code></pre>
  
  <p>What attribute do I need to set here to change the footer color? Thanks.</p>
