PlotGrids and GridFunctions in Google Colab

Hi,

I could not plot grids in Google Colab. I amanaged to show them with the below code:

def Bempp_configure_plotly_browser_state():
    import IPython
    display(IPython.core.display.HTML('''
          <script src="/static/components/requirejs/require.js"></script>
          <script>
            requirejs.config({
              paths: {
                base: '/static/base',
                plotly: 'https://cdn.plot.ly/plotly-1.5.1.min.js?noext',
              },
            });
          </script>
          '''))
    bempp.api.PLOT_BACKEND = "jupyter_notebook"
    plotly.io.renderers.default = 'colab'

Then, before plotting insert the following lines:

Bempp_configure_plotly_browser_state()
grid.plot()

Apologies. I overlooked this message. Thanks for this code snippet!
