if/then: styling for submission

[Michael Pilosov]

@jordanrhall

• please add a copy of the existing .cls file with -final
• edit current .cls file to make hyperlinks blue and remove ragged justification
• make comment above current place where cls is imported about using the -final when submitting. (perhaps note it in the README under heading Final Formatting (2020))

this is now accomplished using the makefile to copy over invisible files from the env folder.
