/**
 * Demonstrates an elegant way how to connect a master list with a bound 
 * details view. It builds a JList of Albums with an attached details panel 
 * that presents the current Album selection. The details panel's components 
 * are bound to the domain using ValueModels returned by a PresentationModel.<p>
 * 
 * This example does not require a custom ListSelectionListener to handle
 * selection changes in the list of Albums. Instead it uses the SelectionInList 
 * as bean channel for the details PresentationModel. And so, whenever the
 * SelectionInList's selection changes, the details PresentationModel will
 * automatically update the bean used to display the details.<p>
 * 
 * In contrast, the MasterDetailsBoundExample uses a ListSelectionListener
 * to handle selection changes in the Album list. This listener then sets
 * the current selection as the details PresentationModel's new bean.<p>
 * 
 * Another variant of this example is the MasterDetailsDelayedReadExample
 * that deferres selection changes for a specified delay. This can be useful
 * if bean changes in the details PresentationModel require time consuming
 * additional operations, for example a database lookup, a heavy computation,
 * or a remote access.
