This class implements the panel that appears in the Publish tab when the ePUB button is selected. See PublishView.SetupEpubControl for initialization. In addition to the controls created in InitializeComponent, this control normally has a browser displaying the book preview which occupies the remaining space. Since this is not a standard control it is easier to create it and insert it when needed, especially since the PublishView needs to manipulate it.
