/**
* 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.
