Why should a reference be kept other than that in self.texts?  Instead 
of keeping track of it somewhere else, would it be sufficient for the 
suptitle method to add a default "suptitle" label to the text object? 
Is there really anything special about the "suptitle" compared to any 
other text object that might be placed on the figure?
