code: public void bind(Object newValue)
      {
      	if (getValue() == null)
      	{
      		setValue(newValue);
      	}	
      	else
      	{
      		setValue2(newValue);
      		setBound(true); 		
      	}
      }
docs: sets the value of the criteria to newValue.
  Used by the ODMG OQLQuery.bind() operation
  BRJ: bind get's called twice so we need to know which value to set
