new components method

I’ve seen some talk on this group and on Github about a new “components” method coming out in 0.9.1 that will make layout less dependent upon HBox/VBox. I’d like to learn more - is there any documentation/explanation/example of what that will look like yet?

An example of it in action is in this PR: https://github.com/bokeh/bokeh/pull/2468

Each of the dictionary values is an actual plot object and then we pass them into a template for rendering

spectrogram_plots = {
    'freq_slider': freq_slider,  # slider
    'gain_slider': gain_slider,  # slider
    'spec': spec,  # image
    'spectrum': spectrum,  # line
    'signal': signal,  # line
    'equalizer': eq  # radial
}

script, divs = components(spectrogram_plots)

     html = flask.render_template("spectrogram.html", bokeh=bokeh, script=script, divs=divs)

We use the divs throughout the html template like this: {{ divs.freq_slider|safe }} etc.

You can see the full template here: https://github.com/birdsarah/bokeh/blob/spectrogram/examples/embed/spectrogram/templates/spectrogram.html
