-/**
- * 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:
- *
- * <pre>
- * "UUDecoder: No begin line."
- * "UUDecoder: Malformed begin line."
- * "UUDecoder: Short Buffer."
- * "UUDecoder: Bad Line Length."
- * "UUDecoder: Missing 'end' line."
- * </pre>
