This is a view which shows a list of options requiring the end-user to make a single selection.
On iOS, this will show a segmented control and will work exactly like our existing Ti.UI.TabbedBar view.
On Android, this view will show a material toggle button group...
The behavior of the new Ti.UI.OptionBar should be near identical to Ti.UI.TabbedBar. We're making this a separate view since TabbedBar is intended to be used by apps that want to set up their own custom tab group interface and should use the native tab widgets.
