Added link to ML Express download.
Add getUrl() method, needed for tests.
Add port in global settings, for use in non-app-specific tests.
Update wording re: security.
Add a delete() method. Reorder methods: read(), write(), delete().
In getErrorMessage(), handle REST errors that come back as text (vs. XML
or JSON). This happens in the Management REST API.
At the end of the Options example, delete the options that were created.
Update autoload scripting to use SPL functions, which are recommended by
PHP.
PHP's exif_read_data() can only get EXIF metadata from JPEG and TIFF, so
check mimetype before getting.
read() can now except extra params. Make getFileMimeType() protected
instead of private.
Override read() and write() to pass 'format=json' param.
Override read() and write() to pass 'format=xml' param.
Minor comment edit in setup files, 'values' => 'settings'
Fix misspelling.
Remove unnecessary require of Match.php.
