/**
* A very fast and memory efficient class to encode and decode to and from
* BASE64 in full accordance with RFC 2045.<br>
* <br>
* On Windows XP sp1 with 1.4.2_04 and later ;), this encoder and decoder is
* about 10 times faster on small arrays (10 - 1000 bytes) and 2-3 times as fast
* on larger arrays (10000 - 1000000 bytes) compared to
* <code>sun.misc.Encoder()/Decoder()</code>.<br>
* <br>
*
* On byte arrays the encoder is about 20% faster than Jakarta Commons Base64
* Codec for encode and about 50% faster for decoding large arrays. This
* implementation is about twice as fast on very small arrays (&lt 30 bytes). If
* source/destination is a <code>String</code> this version is about three times
* as fast due to the fact that the Commons Codec result has to be recoded to a
* <code>String</code> from <code>byte[]</code>, which is very expensive.<br>
* <br>
*
* This encode/decode algorithm doesn't create any temporary arrays as many
* other codecs do, it only allocates the resulting array. This produces less
* garbage and it is possible to handle arrays twice as large as algorithms that
* create a temporary array. (E.g. Jakarta Commons Codec). It is unknown whether
* Sun's <code>sun.misc.Encoder()/Decoder()</code> produce temporary arrays but
* since performance is quite low it probably does.<br>
* <br>
*
* The encoder produces the same output as the Sun one except that the Sun's
* encoder appends a trailing line separator if the last character isn't a pad.
* Unclear why but it only adds to the length and is probably a side effect.
* Both are in conformance with RFC 2045 though.<br>
* Commons codec seem to always att a trailing line separator.<br>
* <br>
*
* <b>Note!</b> The encode/decode method pairs (types) come in three versions
* with the <b>exact</b> same algorithm and thus a lot of code redundancy. This
* is to not create any temporary arrays for transcoding to/from different
* format types. The methods not used can simply be commented out.<br>
* <br>
*
* There is also a "fast" version of all decode methods that works the same way
* as the normal ones, but har a few demands on the decoded input. Normally
* though, these fast verions should be used if the source if the input is known
* and it hasn't bee tampered with.<br>
* <br>
