1. In the module, we created one new, pure, higher-order function, get_updated_tuple.
   Refactor the method Order.get_filtered_info so that it:
        a. is a pure, higher-order function
        b. returns a tuple instead of a list
        c. resides outside the Order class for use in other contexts
        d. uses comprehension(s) instead of map and filter functions

2. Refactor the Order class to use the new function from part 1.

3. Test your work
