Spike automated rest documentation

Looking through http://info.michael-simons.eu/2016/04/17/8-new-features-youll-get-with-spring-boot-1-4/, see if automated rest docs makes sense.

There may be a dependency version mismatch for spring restdocs mvc (1.1.2) and using Spring 5 (5.0.0.M3):

Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.06 sec <<< FAILURE! - in hm.binkley.labs.ApplicationTest
shouldRespondCheerfully()  Time elapsed: 0.125 sec  <<< FAILURE!
java.lang.NoSuchMethodError: org.springframework.http.MediaType.getCharSet()Ljava/nio/charset/Charset;

Problem: SpringFox is not presently working with Spring 5 (missing class, see springfox/springfox#1644). When spiked using Spring 4 and deleting tests (which use JUnit 5 and need Spring 5), nice things happen at http://localhost:8080/swagger-ui.html.
