# Problem: Load a text file containing names, sort it alphabetically, and find the
# product of it's names weight (total of it's letters according to their sequence in the
# alphabet (a=1 etc) and it's position in the list. Find the total of all the name scores
# in the file.
#
# Plan: The file is only 46K, and that's nothing in this day in computing. Just load it into memory,
# sort() it, and iterate over it to find our answer.
