## Annotated class

### Description

The virtual class `Annotated` is used to standardize the storage of metadata with a subclass.

### Details

The `Annotated` class supports the storage of global metadata in a subclass. This is done through the `metadata` slot that stores a list object.

### Accessors

In the following code snippets, `x` is an `Annotated` object.

  `metadata(x)`, `metadata(x) <- value`: Get or set the list holding arbitrary R objects as annotations. May be, and often is, empty.
