/** This implements the "Word Frequency" example on Rosetta Code:
https://rosettacode.org/wiki/Word_frequency
There are a few interesting things to note:
* Frink has a Unicode-aware function, wordList[str], which intelligently
enumerates through the words in a string (and correctly handles compound
words, accented characters, etc.) It returns words, spaces, and
punctuation marks. Results that do not contain alphanumeric characters
are filtered out.
* The file fetched from Project Gutenberg is supposed to be encoded in
UTF-8 character encoding, but their servers incorrectly send that it
is Windows-1252 encoded, so this program fixes that.
* Frink has a Unicode-aware lowercase function, lc[str] which correctly
handles accented characters.
* This program uses the dictionary.increment[key, num] method to help
count words.
