 AttributeUtils provides utilities to simplify working with and reading Attributes in PHP 8.1 and later.
 
-Its primary tool is the Class Analyzer, which allows you to analyze a given class or enum with respect to some attribute class.  Attribute classes may implement various interfaces in order to opt-in to additional behavior, as described below.  The overall intent is to provide a simple but powerful framework for reading metadata off of a class, including with reflection data.

-The class attribute may also opt-in to analyzing various portions of the class, such as its properties, methods, and constants.  It does so by implementing the [`ParseProperties`](src/ParseProperties.php), [`ParseStaticProperties`](src/ParseStaticProperties.php), [`ParseMethods`](src/ParseMethods.php), [`ParseStaticMethods`](src/ParseStaticMethods.php), or [`ParseClassConstants`](src/ParseClassConstants.php) interfaces, respectively.  They all work the same way, so we'll look at properties in particular.

 Note that if the sub-attribute is missing, `null` will be passed to the method.  That is to allow a sub-attribute to have required parameters if and only if it is specified, while keeping the sub-attribute itself optional.  You therefore *must* make the callback method's argument nullable.

 ### Finalizing an attribute
 
-Attributes that opt-in to several functional interfaces may not always have an easy time of knowing when to do default handling.  It may not be obvious when the attribute setup is "done."  Attribute classes may therefore opt-in to the [`Finalizable`](src/Finalizable.php) interface.  If specified, it is guaranteed to be the last method called on the attribute.  The attribute may then do whatever final preparation is appropriate to consider the object "ready."
