Implement flag for input sounds. The property 'soundsEnabled' of LAPickerView determines if a user-input sound is played everytime a column in a LAPickerTableView changes from non-highlighted to highlighted.
Fix bug in LAPickerView layoutSubviews, preventing the subviews to be loaded.
Add 'Toggle Sounds' button to the navigation bar of the Overview example. When press the button toggles the value of the 'soundsEnabled' property in LAPickerView (YES or NO).
