seed_method: determines the method with which the random
number generator is initialized; possible values are:
"builtin": default built-in value used as seed.
"system": derive seed internally from the system clock
"direct": use a positive 32bit integer supplied in seed
as seed. This is automatically chosen if a value for seed
is passed.
"set": use a random seed (32bit) generated by a temporary
instance of _RandomNumbers and reset with it. This way, the
value for seed can be stored for later identical runs.
