From what I understand, we don't actually need to support `snake_case` at all in the PropertyInfo component.I cannot think of any use-case where PropertyAccess would be used to get/set a property value *before* using PropertyInfo to find out information about the property and the values it supports.Since PropertyInfo supports the discovery of property names, which can then be used as identifiers in PropertyAccess, there should be no need to support a naming strategy to map property identifiers from one naming convention to another.---Running `$reflectionExtractor->getProperties($class)` with the following classes:```phpclass X{    public $a;    public $b;    public function getA() {}}// Result: array('a', 'b');``````phpclass Y{    public $A;    public $b;    public function setA() {}}// Result: array('A', 'b');``````phpclass Y{    public $username;    protected $emailAddress;    public $password;    public function getEmailAddress() {}    public function isActive() {}}// Result: array('username', 'emailAddress', 'password', 'active');```Commits-------b2da76c [PropertyInfo] Update List Information from ReflectionExtractor
