\class CntNamesView
\brief

This is the namesview class that shows list of contacts for the user. View contains banner for OVI and a listview that shows actual contacts.
There is also toolbar and menu for navigating between different views. Instance of this class is created by our viewmanager but view itself is
owned by the mainwindow which will also delete it in the end.

*/

/*!
Constructor, initialize member variables.
\a viewManager is the parent that creates this view. \a parent is a pointer to parent QGraphicsItem (by default this is 0)
