Testing 'DefaultList' class
Your job is to create a class (or a function which returns an object)
called DefaultList. The class will have two parameters to be given:
a list, and a default value. The list will obviously be the list that
corresponds to that object. The default value will be returned any time
an index of the list is called in the code that would normally raise an
error (i.e. i > len(list) - 1 or i < -len(list)). This class must also
support the regular list functions extend, append, insert, remove, and pop.

Testing 'DefaultList' class: __getitem__
Called to implement evaluation of self[key]. For sequence types,
the accepted keys should be integers and slice objects.
Note that the special interpretation of negative indexes
(if the class wishes to emulate a sequence type) is up to the
__getitem__() method.
