Support for colaboratory

[langley]

I tried uploading the plotly-scala.ipynb from almond.sh examples to colaboratory.

I got it to run but I don't get any plots in the browser.

I've seen some comments about something similar for python in SO.

Found out that if I add this to a cell plotly renders!

    kernel.publish.html("""
       <script src="/static/components/requirejs/require.js"></script>
       <script>
         requirejs.config({
            paths: {
            base: '/static/base',
            plotly: 'https://cdn.plot.ly/plotly-latest.min.js?noext',
              },
         });
       </script>""")

Now... on to figuring out how to make this easy or automatic!

This SO article talks about registering pre_run_cell logic for the python solution to the problem.
IPython.get_ipython().events.register('pre_run_cell', configure_plotly_browser_state)

The almond module actually does something similar to inject plotly.js into Jupyter classic:

plotly-scala/almond/src/main/scala/plotly/Almond.scala

Lines 28 to 41 in 52f36e3

	s"""require.config({
	| paths: {
	| d3: 'https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.17/d3.min',
	| plotly: 'https://cdn.plot.ly/plotly-${Plotly.plotlyVersion}.min',
	| jquery: 'https://code.jquery.com/jquery-3.3.1.min'
	| },
	|
	| shim: {
	| plotly: {
	| deps: ['d3', 'jquery'],
	| exports: 'plotly'
	| }
	| }
	|});

If we're able to detect that we're running on colab somehow, we could adapt that logic.
