Answer 1

Hi Ashlee,
this is not as heavy reading as you think, you can read the gist of it by skimming through and find all of the important facts you need.
read pp. 4-23 that is the gist of it skip pp. 24-29 (references)
pp. 30-32 are figure discriptions and the rest of the document are figures to give you a visual discription.
