It's in progress still. I have most of the code working, but it's not organized into the chapter structure, yet. I am planning to add a new chapter every ~month

It's in progress still. I have most of the code working, but it's not organized into the chapter structure, yet. I am planning to add a new chapter every ~month (I wish I could do this faster, but I also have some other commitments). Chapter 4 will be either uploaded by the end of this weekend or by the end of next weekend.
