* Function: refresh_verification
*
* Purpose: This function opens the specified object, and checks to see
* that is does not have any attributes on it. It then sends
* a signal to the main process, which will flush the object
* (putting an attribute on the object on disk). This function
* will then refresh the object, and verify that it has picked
* up the new metadata reflective of the added attribute.
*
* Return: 0 on Success, 1 on Failure
