Notes
-----

* Maximum-length LFSR counter - the one period of which equals 2**n-1 where n is width (number of bits) of the counter.
* Initial value of maximum-length LFSR counter can be anything except for 0.
* List of alternative maximal-length polynomials can be found here: http://www.ece.cmu.edu/~koopman/lfsr/index.html
