TODO(ahassani): Describe the directory structure and how-tos.

Glossary

• Alphabet A value that occurs in the input stream. It can be either a
  literal:[0..255], and end of block sign [256], a length[257..285], or a
  distance [0..29].

• Huffman code A variable length code representing the Huffman encoded of an
  alphabet. Huffman codes can be created uniquely using Huffman code length
  array.

• Huffman code array An array which an array index identifies a Huffman code
  and the array element in that index represents the corresponding
  alphabet. Throughout the code, Huffman code arrays are identified by
  vectors with postfix hcodes_.
• Huffman reverse code array An array which an array index identifies an
  alphabet and the array element in that index contains the Huffman code of
  the alphabet. Throughout the code, The Huffman reverse code arrays are
  identified by vectors with postfix rcodes_.
• Huffman code length The number of bits in a Huffman code.
• Huffman code length array An array of Huffman code lengths with the array
  index as the alphabet. Throughout the code, Huffman code length arrays
  are identified by vectors with postfix lens_.
