22 * This is the main factory to instantiate any node within the render
23 * chain of FormEngine. All nodes must implement NodeInterface.
24 *
25 * Nodes are "container" classes of the render chain, "element" classes that
26 * render single elements, as well as "fieldWizard", "fieldInformation" and
27 * "fieldControl" classes which are called by single elements to enrich them.
28 *
29 * This factory gets a string "renderType" and then looks up in a list which
30 * specific class should handle this renderType. This list can be extended with
31 * own renderTypes by extensions, existing renderTypes can be overridden, and
32 * - for complex cases - it is possible to register own resolver classes for single
33 * renderTypes that can return a node class name to override the default lookup list.
