[WIP] Dom component

[glmars]

It's early early early preview of dom component feature (please, see discussion in #128).

The main idea is introducing special syntax to extract peace of a @dom powered code as the separate reusable elements. I'm called it - "dom components".

object Dialog {
  @dom
  def apply(id: Binding[String], children: BindingSeq[Node]): Binding[Div] = <div id={id.bind} class="dialog">{children}</div>
}

implicit final class DialogTags(x: TagsAndTags2.type) {
  @domcomponent
  val dialog = Dialog
}

Which can be used in @dom functions:

@dom val html = <dialog id="123"><button><i>OK</i></button></dialog>

It generates such DOM tree:

<div id="123" class="dialog"><button><i>OK</i></button></div>

❗Hardcode❗ - only dialog tag is considered as a dom component in this preview

I think the efforts of custom components can be split into a separate repository. I had a try in https://github.com/ThoughtWorksInc/dom.scala/

You may want to fork https://github.com/ThoughtWorksInc/dom.scala and hack on it

Unfortunately, your experiment (ThoughtWorksInc/dom.scala@083f8c3#diff-5f9d51a26102bb299d4706844f7678c4R619) breaks mine 😄

Never mind. Both implementation are experiments. I think you can even create a brand new annotation. I imagined an @html annotation in https://www.reddit.com/r/scala/comments/5oo6x0/desktop_gui_and_custom_tags_in_bindingscala/?ref=share&ref_source=link , which is more intuitive than current @dom annotation.

I think this issue has been solved in the Name based XML proposal. html.scala is implemented based on the Name based XML.
