+ * Calls to AddTestCase here. AddTestCase is a function that is defined
+ * in shell.js and takes three arguments:
+ * - a string representation of what is being tested
+ * - the expected result
+ * - the actual result
+ *
+ * For example, a test might look like this:
+ *
+ * var zip = /[\d]{5}$/;
+ *
+ * AddTestCase(
+ * "zip = /[\d]{5}$/; \"PO Box 12345 Boston, MA 02134\".match(zip)",   // description of the test
+ *  "02134",                                                           // expected result
+ *  "PO Box 12345 Boston, MA 02134".match(zip) );                      // actual result
