	 * Constructor.
	 * The toolbox is an integral part of RedBeanPHP providing the basic
	 * architectural building blocks to manager objects, helpers and additional tools
	 * like plugins. A toolbox contains the three core components of RedBeanPHP:
	 * the adapter, the query writer and the core functionality of RedBeanPHP in
	 * OODB.
	 *
	 * Usage:
	 *
	 * <code>
	 * $toolbox = new ToolBox( $oodb, $adapter, $writer );
	 * $plugin  = new MyPlugin( $toolbox );
	 * </code>
	 *
	 * The example above illustrates how the toolbox is used.
	 * The core objects are passed to the ToolBox constructor to
	 * assemble a toolbox instance. The toolbox is then passed to
	 * the plugin, helper or manager object. Instances of
	 * TagManager, AssociationManager and so on are examples of
	 * this, they all require a toolbox. The toolbox can also
	 * be obtained from the facade using: R::getToolBox();
	 *
	 * @param OODB        $oodb    Object Database, OODB
	 * @param DBAdapter   $adapter Database Adapter
	 * @param QueryWriter $writer  Query Writer

	 * $redbean = $toolbox->getRedBean();
	 * $adapter = $toolbox->getDatabaseAdapter();
	 * $writer  = $toolbox->getWriter();

	 * from a toolbox instance. If you are working with the R-object
	 * only, the following shortcuts exist as well:

	 * - R::getDatabaseAdapter()
