Week01 - add_client, add_server, number_checker

Hi Cris,

I'm submitting my pull request for the work assigned for week one.  I realize that it's not before the deadline, so no worries if you don't get to reviewing it.  I did want to make sure that forking etc worked as well.  I do have some questions about best practices that I'll bring up in the next lab.  As for the work, in order to make sure the user inputs 2 numbers (floats or ints), I included number_checker.  I appreciate any feedback.  Right now the server should be running on my remote box, so it should be as easy as just running the client portion and you should get a response...I think.  Thanks for taking a look.
