Extends the rendering pipeline to enhance a component with other features (mixins).
Extend components with features
<custom-form is="validatable">Features are just components, and will be invoked on the element during a render in the same way as the base component. The base component will be invoked first and then any features specified (you can specify multiple features).
ripple('base-component', function(){ this.innerHTML = 'foo' } )
ripple('feature', function(){ this.innerHTML += 'bar' } )<base-component is="feature">foobar<base-component>This pattern is the same as:
d3.select(element)
.call(component)
.call(feature1)
.call(feature2)
.call(feature3)Features may also contribute and mixin their own styles (just extend css attribute).
