def arrange_plots_on_one_canvas(FigureAxTupleArray, title='', SubtitleArray = [], show_fig=True):
    """
    Arranges plots, given in an array of tuples consisting of fig and axs, 
    onto a subplot-figure consisting of 2 horizontal times the lenght of the
    passed (fig,axs)-array divided by 2 vertical subplots 

    Parameters
    ----------
    FigureAxTupleArray : array-like
        array of Tuples(fig, axs) outputted from the other plotting funtions 
        inside optoanalysis
    title : string, optional
        string for the global title of the overall combined figure 
    SubtitleArray : array-like, optional
        array of titles for each figure-set to be plotted, i.e. subplots 
    show_fig : bool, optional
       If True runs plt.show() before returning figure
       if False it just returns the figure object.
       (the default is True, it shows the figure) 

    Returns
    -------
    fig : matplotlib.figure.Figure object
        The figure object created
    axs : list of matplotlib.axes.Axes objects
        The list of axes object created
