/**
 * @short A collection selection dialog.
 *
 * Provides a dialog that lists collections that are available
 * on the Akonadi storage and allows the selection of one or multiple
 * collections.
 *
 * The list of shown collections can be filtered by mime type and access
 * rights. Note that mime types are not enabled by default, so
 * setMimeTypeFilter() must be called to enable the desired mime types.
 *
 * Example:
 *
 * @code
 *
 * using namespace Akonadi;
 *
 * // Show the user a dialog to select a writable collection of contacts
 * CollectionDialog dlg( this );
 * dlg.setMimeTypeFilter( QStringList() << KABC::Addressee::mimeType() );
 * dlg.setAccessRightsFilter( Collection::CanCreateItem );
 * dlg.setDescription( i18n( "Select an address book for saving:" ) );
 *
 * if ( dlg.exec() ) {
 *   const Collection collection = dlg.selectedCollection();
 *   ...
 * }
 *
