It is possible to associate custom metadata with a node using the `setAttribute()` method. This data
can then be retrieved using `hasAttribute()`, `getAttribute()` and `getAttributes()`.

`ClassLike` and `FunctionLike` statements can be converted between each other easily because their
constructor `__construct($name, array $subNodes = [], array $attributes = [])` takes subnodes and
attributes both of which are easy to retrieve, for example if `$node instanceof FunctionLike` then
`new ClassMethod($someName, get_object_vars($node), $node->getAttributes())` will convert it into a
`ClassMethod`.

By default, the parser adds the `startLine`, `endLine`, `startTokenPos`, `endTokenPos`,
`startFilePos`, `endFilePos` and `comments` attributes. `comments` is an array of
`PhpParser\Comment[\Doc]` instances.
