* Converted a couple of existing setup files for intended one here.
* Added single mandatory requirement of CFFI.
* Note that Cython may still be used to produce some component without
requiring it be installed when deploying the API.
* Removed questions 4, 5 and 6 because I decided they were stupid.
* Renumbered question 7 as question 4 and reworded slightly to adjust
for removal of preceding questions. This question pretty much
addresses all the concerns anyway.
