-UNIT TESTS
-----------
-The unit tests are currently split between a few different formats, depending on
-filename and test construction.
-
-- Tests created during the beginning of the project have a test-* prefix. These
-  are more likely to represent integration or system tests rather than unit
-  tests. They should be converted to files with a *Test.js suffix and be
-  refactored to test only the unit.
-- Newer tests use require( 'common' ).testCase() in order to run the tests. The
-  older format separates tests with self-executing functions. The former should
-  be used.
-
-When running the tests, you will notice that the older tests output nothing
-whereas the newer tests output the status of each test in addition to a summary
-at the end of the test case. Ultimately, a test runner will defer final
-statistics until the end of all running tests. The Makefile will need to be
-modified. This sacrifices the ability to use -jN with the tests, but will
-ultimately speed up the tests by eliminating the need to run a separate process
-for each test case (the performance benefit can be seen by running the tests in
-the browser).

 PERFORMANCE TESTS
 -----------------
 Performance tests need to be written for every aspect of the system. They will
