<h3>Log Message</h3>
<pre>Add tests for WXR importer; see <a href="http://gsoc.trac.wordpress.org/ticket/332">#332</a>

- `test_params()`: tests `set_param()`, `get_param()`, `get_all_params()`
- `test_process_author_mappings_standalone()`: tests irreversible problems
  with `process_author_mappings()`
- `test_process_author_mappings_standalone2()`: tests standard operation of
  `process_author_mappings()` (separate from previous item due to
  irreversibility of error)
- `self::set()`: uses Reflection to set otherwise inaccessible properties</pre>
