Rule to transform a class public property into a private property with a getter function

[aszenz]

It should also update all the usages to use the getter instead of property access.

Example:

Original code

class Foo { public $bar; }
// somewhere in code
echo $foo->bar;

Transformed code

class Foo { private $bar; public function getBar() { return $this->bar; } }

// somewhere in code
echo $foo->getBar()
