Deflate: Code Tree for Original Data and Sequence Lengths

This code tree contains all original data, the basic codes for lengths and a control character identifying the end of the current block:

Value	Symbol
0 - 255	original symbols, "literals"
256	control character "end of block"
256 - 285	length codes

The length codes are additionally succeeded by a different number of extra bits (0 - 5 bit) expanding the range of values. This allows to represent sequences with a length between 3 and 258 byte.
