test output updates:

- by default, make tests put all their output into files (under target/surefire-reports/) - with system property -DtestOutputToFile=false to get all output on console;
- have circleci store that output as artifacts;
- run mvn in 'batch mode' in circleci, for quieter output (no download progress, no color codes)

+## Test Logging
+By default, when ran from the command line, mvn surefire will make each test's
+output (e.g., System.out, err, printStackTrace, and all logger calls) go into a 
+file under target/surefire-reports/${className}.txt. 
+
+The system property `-DtestOutputToFile=false` can be given on the command line
+to get all of this output on the console.
+
+In the IDE (e.g,. IntelliJ), output goes to the Console.
+
+In CircleCI, output goes to files, and those files are concatenated together and 
+stored as artifacts.
