This abstract class provides a set of useful default methods that makes it
considerably easier to get started with a new S3 vector class. See
vignette("s3-vector") to learn how to use it to create your own S3

Name of subclass.
The vctr class provides methods for many base generics using a smaller set of generics defined by this package. Generally, you should think carefully before overriding any of the methods that vctrs implements for you as they've been carefully planned to be internally consistent.
