    ''''A parametrized decorator to benchmark the test.
    Setting up the bench can happen in the normal setUp,
    which is applied to all benches identically, and additionally
    the setup parameter, which is bench-specific.
    Parameters
    setup : function
    A function to call once to set up the test.
    number : int
    The number of loops of repeat repeats to run.
    repeat : int
    The number of repeats in each loop.
    warmup : int
    The number of warmup runs of the function.'
