Detailed Description
The TAO_Preference_Interpreter will, given a valid preference string and offers, will order the offers based on the offers' compliance with the preferences.
Each time the order_offer method is invoked, the TAO_Preference_Interpreter stores the offer reference in the order dictated by its evaluation of the preference string. After the TAO_Preference_Interpreter client has finished ordering all the offers, it will extract the offers in order using the remove_offer method.
