The code does the following:
- Check if the file exists and if it is older than 7 days. If either of these conditions are true, download the file from the URI and save it to a file.
- Read the contents of the file into a list of strings
- Find all anagrams in the list of strings by converting each word to a standard form. The standard form is the word with the letters ordered alphabetically.
- Filter the anagrams by finding anagrams which contain a minimum number of words. The default is 2 words.
- Find the words with the most number of anagrams.
- Find the words with the longest anagrams.
- Print the results out to the console.
