Add driver for running method tests

API test cases are not in a maven/gradle project test folder.
IDEs may not automatically configure JUnit test launchers,
and a gradle build command will not automatically run tests.
This class is provided as a convenience until gradle tasks
for running test cases are implemented.

+ *
+ * However, it is easy to manually configure an IDE launcher to run all, some or one
+ * JUnit test, and new gradle tasks should be provided to run all, some, or one test.
