''' Provide a base class for all Bokeh widget models.

In addition to different kinds of plots, various kinds of UI controls (e.g.
sliders, buttons, inputs, etc.) can be included in Bokeh documents. These
widgets can be used in conjunction with ``CustomJS`` callbacks that execute
in the browser,  or with python callbacks that execute on a Bokeh server.
