+/**
+ * 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:
+ *
+ * begin [mode] [filename]
+ *
+ *
+ * This is followed by one or more lines of the form:
+ *
+ * (len)(data)(data)(data) ...
+ *
+ * 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:
+ *
+ *
+ * "UUDecoder: No begin line."
+ * "UUDecoder: Malformed begin line."
+ * "UUDecoder: Short Buffer."
+ * "UUDecoder: Bad Line Length."
+ * "UUDecoder: Missing 'end' line."
+ *
