#pragma mark - TabBarController Sequence

// load an array from the user defaults database
// if the array exists it sorts the tabBar view controller accordingly
// if not, it just fills the tabBarControllerSequence array
// with the default tag values of the view controllers sequence
// defined in the MainWindow.nib file
// tabBarItem tags must be set in MainWindow.nib and
// should start with 0
