Support for using ipywidgets within Bokeh. Ipywidgets are normally used in Jupyter notebooks, but this project allows them to be embedded into a Bokeh application so that they can be used alongside and with Bokeh-based plots and Bokeh widgets. See the separate jupyter_bokeh library for support for using Bokeh plots and widgets in Jupyter and ipywidgets (the opposite case from what ipywidgets_bokeh supports).
