    '''This updates the current checkplotdict with updated values provided.


    Parameters
    ----------

    currentcp : dict or str
        This is either a checkplotdict produced by `checkplot_pickle` above or a
        checkplot pickle file produced by the same function. This checkplot will
        be updated from the `updatedcp` checkplot.

    updatedcp : dict or str
        This is either a checkplotdict produced by `checkplot_pickle` above or a
        checkplot pickle file produced by the same function. This checkplot will
        be the source of the update to the  `currentcp` checkplot.

    outfile : str or None
        The name of the output checkplot pickle file. The function will output
        the new checkplot gzipped pickle file to `outfile` if outfile is a
        filename. If `currentcp` is a file and `outfile`, this will be set to
        that filename, so the function updates it in place.

    outgzip : bool
        This controls whether to gzip the output pickle. It turns out that this
        is the slowest bit in the output process, so if you're after speed, best
        not to use this. This is False by default since it turns out that gzip
        actually doesn't save that much space (29 MB vs. 35 MB for the average
        checkplot pickle).

    pickleprotocol : int or None
        This sets the pickle file protocol to use when writing the pickle:

        If None, will choose a protocol using the following rules:

        - 4 -> default in Python >= 3.4 - fast but incompatible with Python 2
        - 3 -> default in Python 3.0-3.3 - mildly fast
        - 2 -> default in Python 2 - very slow, but compatible with Python 2/3

        The default protocol kwarg is None, this will make an automatic choice
        for pickle protocol that's best suited for the version of Python in
        use. Note that this will make pickles generated by Py3 incompatible with
        Py2.

    verbose : bool
        If True, will indicate progress and warn about problems.

    Returns
    -------

    str
        The path to the updated checkplot pickle file. If `outfile` was None and
        `currentcp` was a filename, this will return `currentcp` to indicate
        that the checkplot pickle file was updated in place.

    Parameters
    ----------

    currentcp : dict or str
        This is either a checkplotdict produced by `checkplot_pickle` above or a
        checkplot pickle file produced by the same function. This checkplot will
        be updated from the `updatedcp` checkplot.

    updatedcp : dict or str
        This is either a checkplotdict produced by `checkplot_pickle` above or a
        checkplot pickle file produced by the same function. This checkplot will
        be the source of the update to the  `currentcp` checkplot.

    outfile : str or None
        The name of the output checkplot pickle file. The function will output
        the new checkplot gzipped pickle file to `outfile` if outfile is a
        filename. If `currentcp` is a file and `outfile`, this will be set to
        that filename, so the function updates it in place.

    outgzip : bool
        This controls whether to gzip the output pickle. It turns out that this
        is the slowest bit in the output process, so if you're after speed, best
        not to use this. This is False by default since it turns out that gzip
        actually doesn't save that much space (29 MB vs. 35 MB for the average
        checkplot pickle).

    pickleprotocol : int or None
        This sets the pickle file protocol to use when writing the pickle:

        If None, will choose a protocol using the following rules:

        - 4 -> default in Python >= 3.4 - fast but incompatible with Python 2
        - 3 -> default in Python 3.0-3.3 - mildly fast
        - 2 -> default in Python 2 - very slow, but compatible with Python 2/3

        The default protocol kwarg is None, this will make an automatic choice
        for pickle protocol that's best suited for the version of Python in
        use. Note that this will make pickles generated by Py3 incompatible with
        Py2.

    verbose : bool
        If True, will indicate progress and warn about problems.

    Returns
    -------

    str
        The path to the updated checkplot pickle file. If `outfile` was None and
        `currentcp` was a filename, this will return `currentcp` to indicate
        that the checkplot pickle file was updated in place.
This updates the current checkplotdict with updated values provided .
