Retrieves a saved visualization based on identifying parameters found on the current URL.
Method returns true or false, depending on whether the URL contains a saved visualization identifier.
If true, the success or failure callback function will be called just as with get. If false, no callbacks
will be called. This method allows callers to use a single method to retrieve saved visualizations, regardless
of how they are identified on the URL.
