Copy editing: chapter 1

Thanks for this terrific resource! This is way more informative than most of the closed-form math texts on Bayesian analysis, and it's great to see the information presented in this interactive format as well.

I made some copy edits in Chapter 1 for flow, language, and continuity. If you find these useful, I can do more in later chapters as well.

Nothing substantive has been changed except that I added short blurbs about the physical interpretations of the Poisson and exponential distributions. I understand that they're used mostly as a basis for a discussion of their form, but knowing what they represent may help spark readers' intuition.
