The CodePoint code kata is simple. There is a single test where you have to read a secret message
from a file called codepoints.txt and translate the file into an ImmutableList of String and
then collect all the characters into a CharBag so they can be counted to verify that you have translated
the message correctly. You should finally write the ImmutableList of String to a file so you
can read the secret message.
Here's an example of translating a comma separated String of code point values to a human readable String.
