Description:
 def _repeat_iter(input_iter):
 """Iterate over the input iter values. Then repeat the last value indefinitely. This is useful to repeat seed values when an insufficient number of seeds are provided. E.g. KISS(1) effectively becomes KISS(1, 1, 1, 1), rather than (if we just used default values) KISS(1, default-value, default-value, default-value) It is better to repeat the last seed value, rather than just using default values. Given two generators seeded with an insufficient number of seeds, repeating the last seed value means their states are more different from each other, with less correlation between their generated outputs.
