/**
 * Object is the base class that implements the *property* feature.
 *
 * A property is defined by a getter method (e.g. `getLabel`), and/or a setter method (e.g. `setLabel`). For example,
 * the following getter and setter methods define a property named `label`:
 *
 * ```php
 * private $_label;
 *
 * public function getLabel()
 * {
 * return $this->_label;
 * }
 *
 * public function setLabel($value)
 * {
 * $this->_label = $value;
 * }
 * ```
 *
 * Property names are *case-insensitive*.
 *
 * A property can be accessed like a member variable of an object. Reading or writing a property will cause the invocation
 * of the corresponding getter or setter method. For example,
 *
 * ```php
 * // equivalent to $label = $object->getLabel();
 * $label = $object->label;
 * // equivalent to $object->setLabel('abc');
 * $object->label = 'abc';
 * ```
 *
 * If a property has only a getter method and has no setter method, it is considered as *read-only*. In this case, trying
 * to modify the property value will cause an exception.
 *
 * One can call [[hasProperty()]], [[canGetProperty()]] and/or [[canSetProperty()]] to check the existence of a property.
 *
 * Besides the property feature, Object also introduces an important object initialization life cycle. In particular,
 * creating an new instance of Object or its derived class will involve the following life cycles sequentially:
 *
 * 1. the class constructor is invoked;
 * 2. object properties are initialized according to the given configuration;
 * 3. the `init()` method is invoked.
 *
 * In the above, both Step 2 and 3 occur at the end of the class constructor. It is recommended that
 * you perform object initialization in the `init()` method because at that stage, the object configuration
 * is already applied.
 *
 * In order to ensure the above life cycles, if a child class of Object needs to override the constructor,
 * it should be done like the following:
 *
 * ```php
 * public function __construct($param1, $param2, ..., $config = [])
 * {
 * ...
 * parent::__construct($config);
 * }
 * ```
 *
 * That is, a `$config` parameter (defaults to `[]`) should be declared as the last parameter
 * of the constructor, and the parent implementation should be called at the end of the constructor.
