+   * Run tagger on Moby Dick and compare result to pre-computed XCAS. This test case is a bit
+   * brittle. First of all, it requires the uimaj-core project as a neighbor, otherwise it won't
+   * find moby.txt, the test input.  Secondly, the reference output is only a list of POS tags.
+   * This is so the file doesn't get so big.  Finally, if anything changes, even improvements, this
+   * test will most likely fail and will need to be updated.  There's an unused method below that
+   * can be used to write a new set of POS tags when the old ones become obsolete.
