* Updates all the examples in CrashCourse.tex up to the functions section
This adds more REPL annotations for the exercise checker in the Programming
Cryptol book. There is still more work needed to support many of the examples in
the functions section (and presumably the rest of the book as well), so I think
this is a logical stopping point for now until we add a feature that lets you
write out a file and load it into the repl.
