+    \class CpThemeControl
+    \brief CpThemeControl creates and controls two views for Theme Changer plugin and handles
+	user interaction to preview and change the themes.
+
+	It creates a list view of the themes.  When a list item is selected, it creates a preview
+	of the theme icon using a CpThemePreview class.  
+
+	This class also connects to the theme server using the HbThemeChanger and sets the theme
+	based on user interaction with the views.
