/// * This interface acts as a container for an object serialized using the
/// * structured clone algorithm.
/// *
/// * You can copy an object into an nsIStructuredCloneContainer using
/// * initFromJSVal or initFromBase64. It's an error to initialize an
/// * nsIStructuredCloneContainer more than once.
/// *
/// * Once you've initialized the container, you can get a copy of the object it
/// * stores by calling deserializeToVariant. You can also get a base-64-encoded
/// * string containing a copy of the container's serialized data, using
/// * getDataAsBase64.
