Copy a resource to a new location.
webdav.copyResource(sourceResourceURI, destinationResourceURI, [callback])
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
The CopyResource method will copy the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.
This method is associated with the Depth property. If Depth is set to "0", the class will copy only SourceResourceURI. If Depth is set to "infinity", the class will copy SourceResourceURI and its entire subtree to locations relative to it.
If the user has acquired a LockResource of infinite depth on either DestinationResourceURI or any collection it is under, SourceResourceURI will be added to that lock.
