BUGGY CONCEPT CODE!

This is concept code for a object oriented Forms and Rendering API in Drupal.

The basic class tree:

abstract class DrupalObject:
  A simple callback mechanism for inter-object communication (aka Observer pattern or Signals and Slots)
  
abstract class DrupalElement extends DrupalObject:
  A not-so-simple class. Implements ArrayAcess to access child elements by treating the object as an array.
  Several children managment features. Implements Iterator to manipulate over what foreach iterates. 
  And more. See the docs.

abstract class DrupalWidget extends DrupalElement:
  Adds rendering (theming) functionality to a DrupalElement
  
abstract class DrupalForm extends DrupalWidget:
  FAPI ;)
  
abstract class DrupalFormWidget extends DrupalWidget
  Individual input-widgets like Textfield etc. extend that class.
