-/**
- * This class defines the decoding half of character encoders.
- * A character decoder is an algorithim for transforming 8 bit
- * binary data that has been encoded into text by a character
- * encoder, back into original binary form.
- *
- * The character encoders, in general, have been structured
- * around a central theme that binary data can be encoded into
- * text that has the form:
- *
- * <pre>
- * [Buffer Prefix]
- * [Line Prefix][encoded data atoms][Line Suffix]
- * [Buffer Suffix]
- * </pre>
- *
- * Of course in the simplest encoding schemes, the buffer has no
- * distinct prefix of suffix, however all have some fixed relationship
- * between the text in an 'atom' and the binary data itself.
- *
- * In the CharacterEncoder and CharacterDecoder classes, one complete
- * chunk of data is referred to as a <i>buffer</i>. Encoded buffers
- * are all text, and decoded buffers (sometimes just referred to as
- * buffers) are binary octets.
- *
- * To create a custom decoder, you must, at a minimum, overide three
- * abstract methods in this class.
- * <DL>
- * <DD>bytesPerAtom which tells the decoder how many bytes to
- * expect from decodeAtom
- * <DD>decodeAtom which decodes the bytes sent to it as text.
- * <DD>bytesPerLine which tells the encoder the maximum number of
- * bytes per line.
- * </DL>
- *
- * In general, the character decoders return error in the form of a
- * CEFormatException. The syntax of the detail string is
- * <pre>
- * DecoderClassName: Error message.
- * </pre>
- *
- * Several useful decoders have already been written and are
- * referenced in the See Also list below.

- * This class implements a Berkeley uu character decoder. This decoder
- * was made famous by the uudecode program.
- *
- * The basic character coding is algorithmic, taking 6 bits of binary
- * data and adding it to an ASCII ' ' (space) character. This converts
- * these six bits into a printable representation. Note that it depends
- * on the ASCII character encoding standard for english. Groups of three
- * bytes are converted into 4 characters by treating the three bytes
- * a four 6 bit groups, group 1 is byte 1's most significant six bits,
- * group 2 is byte 1's least significant two bits plus byte 2's four
- * most significant bits. etc.
- *
- * In this encoding, the buffer prefix is:
- * <pre>
- * begin [mode] [filename]
- * </pre>
- *
- * This is followed by one or more lines of the form:
- * <pre>
- * (len)(data)(data)(data) ...
- * </pre>
- * where (len) is the number of bytes on this line. Note that groupings
- * are always four characters, even if length is not a multiple of three
- * bytes. When less than three characters are encoded, the values of the
- * last remaining bytes is undefined and should be ignored.
- *
- * The last line of data in a uuencoded buffer is represented by a single
- * space character. This is translated by the decoding engine to a line
- * length of zero. This is immediately followed by a line which contains
- * the word 'end[newline]'
- *
- * If an error is encountered during decoding this class throws a
- * CEFormatException. The specific detail messages are:

-/**
- * This class implements a Berkeley uu character encoder. This encoder
- * was made famous by uuencode program.
- *
- * The basic character coding is algorithmic, taking 6 bits of binary
- * data and adding it to an ASCII ' ' (space) character. This converts
- * these six bits into a printable representation. Note that it depends
- * on the ASCII character encoding standard for english. Groups of three
- * bytes are converted into 4 characters by treating the three bytes
- * a four 6 bit groups, group 1 is byte 1's most significant six bits,
- * group 2 is byte 1's least significant two bits plus byte 2's four
- * most significant bits. etc.
- *
- * In this encoding, the buffer prefix is:
- * <pre>
- * begin [mode] [filename]
- * </pre>
- *
- * This is followed by one or more lines of the form:
- * <pre>
- * (len)(data)(data)(data) ...
- * </pre>
- * where (len) is the number of bytes on this line. Note that groupings
- * are always four characters, even if length is not a multiple of three
- * bytes. When less than three characters are encoded, the values of the
- * last remaining bytes is undefined and should be ignored.
- *
- * The last line of data in a uuencoded file is represented by a single
- * space character. This is translated by the decoding engine to a line
- * length of zero. This is immediately followed by a line which contains
- * the word 'end[newline]'
