I am adding convenience APIs to my subclass, `Domite`.

##Rendering

 - `aSilk << anObject` uses double-dispatch via `renderOnSilk:`. This allows creating widgets (no formal superclass, anything with `renderOnSilk:` is a widget), as well as incorporating blocks: `aSilk << aBlock` runs the block, passing aSilk as a parameter.!

!Silk methodsFor: 'writing'!

nextPut: anObject
	"Double-dispatches anObject via renderOnSilk: message.
	If a message returns nil, this fallbacks to superclass.
	Otherwise, it is assumed renderOnSilk: did its job."

	(anObject renderOnSilk: self)
		ifNil: [ super nextPut: anObject ]
