+---------------------

+This is almost the same as adding a new regression test:
+1) Create the example under examples/
+2) run the test with the environment variable TEST_GENERATE=1, e.g.:
+   $ TEST_GENERATE=1 ctest -C Examples -R exampleNNN
+   (this will generate a exampleNNN-expected.txt file which is used for regression testing)

+4) run the test normally and verify that it passes:
+  $ ctest -C Examples -R exampleNNN
