      Auxiliary function responsible for the creation of a directory where Bokeh figures will be
      stored.
      The "active" output file for Bokeh will also be updated for the new one.

      Description
      -----------
      To ensure that Bokeh plots are correctly observed in the HTML version of the Notebooks, it is
      necessary to embed the plots inside Iframes.
  
      Taking this into consideration, the source file of the plot is mandatory to use an Iframe, and
      this function ensures the generation of a Bokeh file for each plot, storing it in an adequate
      place.
