* Get the size of the indicated datastream.

* Note that this only works for Inline XML and Managed datastream, as Fedora
* does not know anything about external or redirect streams, other than a URI.
* If run on an external or redirect stream, Fedora (and therefore this
* function) will return the integer value '0'.
* This function requires the use of the API-M method getDatastream, and defaults
* to returning '0' if it is not accessible.
*
* @param $pid string
* A string containing the PID of a Fedora object.
* @param $dsid string
* A string containing the datastream ID of datastream on the Fedora object
* indicated by the PID.
* @param $quiet boolean
* A boolean indicating whether SOAP errors should be displayed.
* @return integer
* An integer representing the size of the datastream, or zero if it could not be determined.
