Only encoder
4 
This version works correctly, it is tested with testcase.jpg
5 
The translation into real huffman codes works.
6 
Changed: If huffman wants to send 0xFFxx (FF in one byte) than there must be 0x00 inserted between FF and xx
7 
possible fault in finish send:
8 
-must it be filled up with zeros?          YES
9 
-must it be filled up to one bye? or 2 byte? --> in this code there is filled up to 2 bytes, but I (joris) thinks this must be filled up to 1 byte.
10 
 still dont know
11 
- 24-11-05 code clean up
12 
- 24-11-05 tables added for color
