/**
* Report whether the given key is found.
* Determine whether a key is in a mapping, and access its value.
*
* This method can only be called on mapping nodes.
*
* Returns:
* A pointer to the value of the given key, or null if not found.
*
* Be careful! Modifying the mapping with any other function can
* invalidate the pointer.
*
* Params: key = Key to search for.
*
* Returns: A pointer to the value (as a Node) corresponding to key,
* or null if not found.
*
* Note: Any modification to the node can invalidate the returned
* pointer.
