Detailed Description

Galois LFSR pseudo-random source.

Parameters:

degree	Degree of shift register must be in [1, 32]. If mask is 0, the degree determines a default mask (see digital_impl_glfsr.cc for the mapping).
repeat	Set to repeat sequence.
mask	Allows a user-defined bit mask for indexes of the shift register to feed back.
seed	Initial setting for values in shift register.
