/**
 * Dialog class to select a footprint from the libraries. This is the master
 * View class in a Model-View-Adapter (mediated MVC) architecture. The other
 * pieces are in:
 *
 * - Adapter: CMP_TREE_MODEL_ADAPTER in common/cmp_tree_model_adapter.h
 * - Model: CMP_TREE_NODE and descendants in common/cmp_tree_model.h
 *
 * Because everything is tied together in the adapter class, see that file
 * for thorough documentation. A simple example usage follows:
 *
 *     // Create the adapter class
 *     auto adapter( FP_TREE_MODEL_ADAPTER::Create( Prj().PcbFootprintLibs() ) );
 *
 *     // Perform any configuration of adapter properties here
 *     adapter->SetPreselectNode( "LIB_NICKNAME", "FP_NAME", 2 );
 *
 *     // Initialize model from #FP_LIB_TABLE
 *     libNicknames = libs->GetLogicalLibs();
 *
 *     for( auto nickname : libNicknames )
 *     {
 *         adapter->AddLibrary( nickname );
 *     }
 *
 *     // Create and display dialog
 *     DIALOG_CHOOSE_FOOTPRINT dlg( this, title, adapter, 1 );
 *     bool selected = ( dlg.ShowModal() != wxID_CANCEL );
 *
 *     // Receive part
 *     if( selected )
 *     {
 *         int unit;
 *         #LIB_ID id = dlg.GetSelectedAlias( &unit );
 *         do_something( id, unit );
 *     }
