"""
This script, using a dictionary provided by github.com/dwyl/english-words,
sorts each word in the dictionary (let's call this the sorted_word of any given
word).

The script in create_anagram_dictionary(), creates a dictionary that uses
orted_words as keys with their values being an array of words that shares that
same sorted_word.

cache_anagram_dictionary() creates a .txt file (data/anagram_dictionary.txt)
where the dictionary created in create_anagram_dictionary() is stored in the
format:
<sorted_word>:<word>|<word2>,...

This script only needed to be run once, to create data/anagram_dictionary.txt.
After that, the program will use that file to (somewhat) quickly re-create the
dictionary on each run.
