/**
 * The context is scanned for {@link OptionKey} instances.  If none are found a message is displayed saying there are no options.  A context is loaded
 * only once - the {@link OptionKey} instances are cached. The {@link DefaultOptionBinder} binds a UI Field with an {@link Option} value, combined with a {@link Converter} instance to enable conversion to and from the type needed for presentation (usually String).  <p>
 * Options are displayed in a grid of 2 columns, the first column containing a Vaadin component to display the option value and the second a button to
 * reset the value to default. The component and button are each wrapped in a FormLayout to position the caption to the left of the value<p>
 * A value change listener is attached to the Vaadin component to change the option value in response to the user changing the value ion the component.
