Selecting items in tables

Tables can listen to clicks on rows. What you need to do is to add an ItemClickListener method to the table:

table.addItemClickListener(this);

Because we are passing a reference to our UI class (this), we must implement ItemClickListener in our BoxwordsUI class:

public class BoxwordsUI extends UI implements ItemClickListener {
  public void itemClick(ItemClickEvent event) { }
}

The itemClick method will be called every time the user clicks on a table row. Let's add that behavior right away.
