+# Description:	Implementation of a Galois LFSR 
+#               The bitstream is provided by the generator function
+#               GLFSR.states(). The 'repeat' flag controls whether the
+#               generator stops once the LFSR overflows or whether it
+#               continues perpetually.

+# History:	None yet
