-/**
- * Encodes and decodes to and from Base64 notation.
- *
- * <p>
- * Homepage: <a href="http://iharder.net/base64">http://iharder.net/base64</a>.
- * </p>
- *
- * <p>
- * Change Log:
- * </p>
- * <ul>
- *   <li>v2.2.1 - Fixed bug using URL_SAFE and ORDERED encodings. Fixed bug
- *     when using very small files (~&lt; 40 bytes).</li>
- *   <li>v2.2 - Added some helper methods for encoding/decoding directly from
- *     one file to the next. Also added a main() method to support command
- *     line encoding/decoding from one file to the next. Also added these
- *     Base64 dialects:
- *     <ol>
- *       <li>The default is RFC3548 format.</li>
- *       <li>Using Base64.URLSAFE generates URL and file name friendly format as
- *         described in Section 4 of RFC3548.
- *         http://www.faqs.org/rfcs/rfc3548.html</li>
- *       <li>Using Base64.ORDERED generates URL and file name friendly format
- *         that preserves lexical ordering as described in
- *         http://www.faqs.org/qa/rfcc-1940.html</li>
- *     </ol>
- *     <p>
- *     Special thanks to Jim Kellerman at <a href="http://www.powerset.com/">
- *     http://www.powerset.com/</a> for contributing the new Base64 dialects.
- *   </li>
- *
- *   <li>v2.1 - Cleaned up javadoc comments and unused variables and methods.
- *     Added some convenience methods for reading and writing to and from files.
- *   </li>
- *   <li>v2.0.2 - Now specifies UTF-8 encoding in places where the code fails on
- *     systems with other encodings (like EBCDIC).</li>
- *   <li>v2.0.1 - Fixed an error when decoding a single byte, that is, when the
- *     encoded data was a single byte.</li>
- *   <li>v2.0 - I got rid of methods that used booleans to set options. Now
- *     everything is more consolidated and cleaner. The code now detects when
- *     data that's being decoded is gzip-compressed and will decompress it
- *     automatically. Generally things are cleaner. You'll probably have to
- *     change some method calls that you were making to support the new options
- *     format (<tt>int</tt>s that you "OR" together).</li>
- *   <li>v1.5.1 - Fixed bug when decompressing and decoding to a byte[] using
- *     <tt>decode( String s, boolean gzipCompressed )</tt>. Added the ability to
- *     "suspend" encoding in the Output Stream so you can turn on and off the
- *     encoding if you need to embed base64 data in an otherwise "normal" stream
- *     (like an XML file).</li>
- *   <li>v1.5 - Output stream pases on flush() command but doesn't do anything
- *     itself. This helps when using GZIP streams. Added the ability to
- *     GZip-compress objects before encoding them.</li>
- *   <li>v1.4 - Added helper methods to read/write files.</li>
- *   <li>v1.3.6 - Fixed OutputStream.flush() so that 'position' is reset.</li>
- *   <li>v1.3.5 - Added flag to turn on and off line breaks. Fixed bug in input
- *     stream where last buffer being read, if not completely full, was not
- *     returned.</li>
- *   <li>v1.3.4 - Fixed when "improperly padded stream" error was thrown at the
- *     wrong time.</li>
- *   <li>v1.3.3 - Fixed I/O streams which were totally messed up.</li>
- * </ul>
- *
- * <p>
- * I am placing this code in the Public Domain. Do with it as you will. This
- * software comes with no guarantees or warranties but with plenty of
- * well-wishing instead!
- * <p>
- * Please visit <a href="http://iharder.net/base64">http://iharder.net/base64</a>
- * periodically to check for updates or to contribute improvements.
