 /**
  * Runs javadoc and then runs regression tests on the resulting output.
  * This class currently contains three tests:
  * <ul>
  * <li> String search: Reads each file, complete with newlines,
  *      into a string.  Lets you search for strings that contain
  *      newlines.  String matching is case-sensitive.
  *      You can run javadoc multiple times with different arguments,
  *      generating output into different destination directories, and
  *      then perform a different array of tests on each one.
  *      To do this, the run method accepts a test array for testing
  *      that a string is found, and a negated test array for testing
  *      that a string is not found.
  * <li> Run diffs: Iterate through the list of given file pairs
  *      and diff the pairs.
  * <li> Check exit code: Check the exit code of Javadoc and
  *      record whether the test passed or failed.
  * </ul>
