Apply document-level formatting and rearrange the array-in-struct discussion.

Formatting:
- add visual separation of figures from text
- prevent "formula"-style code fragments from page breaking
- (thereby prevent code formula broken at end of page from mistakenly restarting the reader in a code figure at the top of the next page)
- give short+long figure captions
- assure descriptive captions
- remove Title-Like Captialization in Captions
- turn a couple figures into tables where the figure visual separator looks bad

Array-in-struct
- remove lingering use of "accordion"
- call it Dynamic Array Member
- oranize discussion as, first explain example, then argue feature is good
