Determine if a word or phrase is an isogram.
An isogram (also known as a "nonpattern word") is a word or phrase without a repeating letter, however spaces and hyphens are allowed to appear multiple times.
Examples of isograms:
- lumberjacks
- background
- downstream
- six-year-old
The word isograms, however, is not an isogram, because the s repeats.

Execute the tests with:
$ cargo testAll but the first test have been ignored. After you get the first test to
pass, remove the ignore flag (#[ignore]) from the next test and get the tests
to pass again. The test file is located in the tests directory. You can
also remove the ignore flag from all the tests to get them to run all at once
if you wish.
Make sure to read the Modules chapter if you haven't already, it will help you with organizing your files.
