-/**
- * DibiObject is the ultimate ancestor of all instantiable classes.
- *
- * DibiObject is copy of Nette\Object from Nette Framework (http://nette.org).
- *
- * It defines some handful methods and enhances object core of PHP:
- *   - access to undeclared members throws exceptions
- *   - support for conventional properties with getters and setters
- *   - support for event raising functionality
- *   - ability to add new methods to class (extension methods)
- *
- * Properties is a syntactic sugar which allows access public getter and setter
- * methods as normal object variables. A property is defined by a getter method
- * and optional setter method (no setter method means read-only property).
- * <code>
- * $val = $obj->label;     // equivalent to $val = $obj->getLabel();
- * $obj->label = 'Nette';  // equivalent to $obj->setLabel('Nette');
- * </code>
- * Property names are case-sensitive, and they are written in the camelCaps
- * or PascalCaps.
- *
- * Event functionality is provided by declaration of property named 'on{Something}'
- * Multiple handlers are allowed.
- * <code>
- * public $onClick;                // declaration in class
- * $this->onClick[] = 'callback';  // attaching event handler
- * if (!empty($this->onClick)) ... // are there any handlers?
- * $this->onClick($sender, $arg);  // raises the event with arguments
- * </code>
- *
- * Adding method to class (i.e. to all instances) works similar to JavaScript
- * prototype property. The syntax for adding a new method is:
- * <code>
- * MyClass::extensionMethod('newMethod', function(MyClass $obj, $arg, ...) { ... });
- * $obj = new MyClass;
- * $obj->newMethod($x);
- * </code>
