A very fast and memory efficient class to encode and decode to and from BASE64 in full accordance with RFC 2045.
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
sun.misc.Encoder()/Decoder().
On byte arrays the encoder is about 20% faster than Jakarta Commons Base64 Codec for encode and about 50% faster for
decoding large arrays.
