    Parameters
    ----------
    kwargs : dict
        Dictionary of labels and their values.
    aliases : dict
        Dictionary of label names and their list of aliases.

    Returns
    -------
    out_kwargs : dict
        Dictionary of labels and their values.

    Notes
    -----
    This function checks all labels in `kwargs` for if they are listed within
    the the `aliases` dictionary. If so, it standardizes this label in `kwargs`
    to the standard label, as defined by the keys of `aliases`.
