Question
This problem has you write a nested loop to process a list of list of int, and accumulate a list of list of int. The starter code
provides an accumulator for the result and a loop over the lists, and you need to write the code that checks whether sublist contains only
even ints.
You'll probably want a one-way flag: a Boolean variable that starts out as True and is set to False if you find an odd int in the sublist. You'll
need to check the value of this variable to figure out whether to append sublist to the even_lists accumulator.

**"Return a list of the lists in 1st that contain only even integers.
