Creates an object and sets its properties without calling its constructor nor any other methods.

For example:

// creates an empty instance of Foo
Instantiator::instantiate(Foo::class);

// creates a Foo instance and sets one of its properties
Instantiator::instantiate(Foo::class, ['propertyName' => $propertyValue]);

// creates a Foo instance and sets a private property defined on its parent Bar class
Instantiator::instantiate(Foo::class, [], [
Bar::class => ['privateBarProperty' => $propertyValue],
]);

Instances of ArrayObject, ArrayIterator and SplObjectHash can be created
by using the special "\0" property name to define their internal value:

// creates an SplObjectHash where $info1 is attached to $obj1, etc.
Instantiator::instantiate(SplObjectStorage::class, ["\0" => [$obj1, $info1, $obj2, $info2...]]);

// creates an ArrayObject populated with $inputArray
Instantiator::instantiate(ArrayObject::class, ["\0" => [$inputArray]]);

@param string $class             The class of the instance to create
@param array  $properties        The properties to set on the instance
@param array  $privateProperties The private properties to set on the instance,
keyed by their declaring class

@return object The created instance

@throws ExceptionInterface When the instance cannot be created
Creates an object and sets its properties without calling its constructor nor any other methods .
