ExpansionPanelRadio class

An expansion panel that allows for radio-like functionality. This means that at any given time, at most, one ExpansionPanelRadio can remain expanded.

A unique identifier value must be assigned to each panel. This identifier allows the ExpansionPanelList to determine which ExpansionPanelRadio instance should be expanded.

See ExpansionPanelList.radio for a sample implementation.
