I had a happy victory over intense confusion. I put FScript.framework in home/library/ but project builder couldn't find it. After getting terrified that I would have to navigate gobs of fundamental hypertext, my brain jumped tracks to the files window wherein were frameworks. How did they get there? Could I put them there? I dragged the folder FScript.framework to the frameworks in files window and project builder was able to find the framework.
Then, I had to leave my macintosh to get ready for an appointment. When I came back to my mac, I was ready to experiment and finished reading the article in the remainder of the evening.
The first experiment that I did was to make a FSWindowController class inheriting from NSWindowController with the method expt for experiment. Interface builder had a DoIt button and that was connected to the single WindowController action expt.

That is why it is beautiful.
