Base class used by [`StorageRef`], [`NodeMetaRef`], [`ItemStackMetaRef`],
and [`PlayerMetaRef`].
Note: If a metadata value is in the format `${k}`, an attempt to get the value
will return the value associated with key `k`. There is a low recursion limit.
This behavior is **deprecated** and will be removed in a future version. Usage
of the `${k}` syntax in formspecs is not deprecated.
### Methods
* `contains(key)`: Returns true if key present, otherwise false.
