Setting up a subdirectory for week 11 in-class work

---

cd into your cs21/class/ subdirectory and create a new directory named 'week11', then cd into that directory:

$ cd cs21/class                     # cd into your cs21/class subdirectory
$ pwd	          
  /home/your_user_name/cs21/class

$ mkdir week11                      # make a subdirectory named week11   
$ cd week11                         # cd into it
$ pwd           
  /home/your_user_name/cs21/class/week11

Now copy over all the files from my public/cs21/week11 directory into your week11 directory (remember to add the dot as the destination of the cp command). From your week11 directory:

$ cp ~newhall/public/cs21/week11/* .
