!Silk commentStamp!
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.

##Convenience

 - `aCssSelectorString asSilk` returns Silk wrapping an element at a selector.
 - `anObject inSilk` returns anObject rendered in a document fragment.

##Element creation

These messages use DNU to dynamically create
elements with any (letters-and-numbers) tag name,
Next samples show this on an example of `<div>`.

 - `Silk DIV` is shortcut for `Silk newElement: 'div'`.!

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 ]
