Class with unit tests

I worked thru the changes in the email:
cleaning up the names
removing the duplicate unittests.
Hi Sarah,

I am working thru the revisions and updating the ones I understand.  This one, I am not so clear on.

I am still a little vague on init and what it does.  I don’t want to break the code, so I am going to leave this one alone for now.

thanks,
Matt
