    Applies a technique of label-splitting, to distinguish between different meanings of the same
    activity. The result is a Pandas dataframe where the label-splitting has been applied.

    Minimum Viable Example:

        import pm4py
        from pm4py.algo.label_splitting import algorithm as label_splitter

        log = pm4py.read_xes("tests/input_data/receipt.xes")
        log2 = label_splitter.apply(log)


    Parameters
    ---------------
    log
        Event log
    parameters
        Variant-specific parameters

    Returns
    ---------------
    dataframe
        Pandas dataframe with the re-labeling

    return exec_utils.get_variant(variant).apply(log, parameters)
