Minimal testcase with multiple runs

import numpy as np
from simkernel import Experiment

def sim():
    return True

xp = Experiment(sim)
res = xp(repeat=3)

np.testing.assert_array_equal(res, [True, True, True])

This is trivial (and dumb) for deterministic functions, but is useful for experiments that measure computation time (cf. timeit) or for simple stochastic experiments (without the need for Common Random Numbers).
