	32	* VLADIMIR Z. MESAROVIC , RAGHUNATH RAO, MIROSLAV V. DOKIC, and SACHIN DEO
	33	* AES paper 5436
	34	*
	35	* 2 methods are used for huffman decoding:
	36	* - binary search
	37	* - 2-step table lookup
	38	*
	39	* The choice of the "optimal" method is based on the fact that if the
	40	* memory size for the Two-step is exorbitantly high then the decision
	41	* is Binary search for that codebook. However, for marginally more memory
	42	* size, if Twostep outperforms even the best case of Binary then the
	43	* decision is Two-step for that codebook.
	44	*
	45	* The following methods are used for the different tables.
	46	* codebook "optimal" method
	47	* HCB_1 2-Step
	48	* HCB_2 2-Step
	49	* HCB_3 Binary
