-/* How this works:
- * B(2,4) means:
- * 	Alphabet size = 2 (binary)
- * 	Code length = 4
- * The length of the bitstream is (2 ^ 4) + (4 - 1) = 19 bits
- * The primitive polynomials come from the de_bruijn_polys[] array (one for each code length)
- * The shift register is init with 1 and shifted left each step
- * The polynomial is kept on the right, and used as a AND mask applied on the corresponding shift register bits
- * The resulting bits are XORed together to produce the new bit pushed in the shift register
- *
- * 		0001 (init)
- * AND	1001 (polynomial)
- *      0001 XOR'd -> 1
- *
- * 		00011 (shift left)
- * AND	 1001
- *       0001 XOR'd -> 1
- *
- * 		000111 (shift left)
- * AND	  1001
- *        0001 XOR'd -> 1
- *
- * 		0001111 (shift left)
- * AND	   1001
- *         1001 XOR'd -> 0
- *
- * 		00011110 (shift left)
- * AND	    1001
- *          1000 XOR'd -> 1
- * ...
- * After 16 steps: (0+) 000111101011001000
- * Each of the 16 possible values appears in the sequence:
- * -0000-111101011001000 0
- * 0-0001-11101011001000 1
- * 0000111101011-0010-00 2
