/* This module is the Huffman encoder. It takes in the quantized outputs
from the quantizer, and creates the Huffman codes from these value. The
output from this module is the jpeg code of the actual pixel data. The jpeg
file headers will need to be generated separately. The Huffman codes are constant,
and they can be changed by changing the parameters in this module. */

If there aren't any nonzero elements left, then the last bits in the JPEG stream
will be the end of block code. The purpose of this register is to determine if the
zero run length code 15-0 should be used or not. It should be used if there are 15 or more
zeros in a row, followed by a nonzero value. If there are only zeros left in the block,
then end_of_block will be 1. If there are any nonzero values left in the block, end_of_block
will be 0. */

/* These Y DC and AC code lengths, run lengths, and bit codes
were created from the Huffman table entries in the JPEG file header.
For different Huffman tables for different images, these values
below will need to be changed. I created a matlab file to automatically
create these entries from the already encoded JPEG image. This matlab program
won't be any help if you're starting from scratch with a .tif or other
raw image file format. The values below come from a Huffman table, they
do not actually create the Huffman table based on the probabilities of
each code created from the image data. You will need another program to
create the optimal Huffman table, or you can go with a generic Huffman table,
which will have slightly less than the best compression.*/
