Instread of an explicit 'enabled' bool, this uses the presence of the
event handler to determine if a widget is enabled or not. This means
that if you've not passed a handler, your widget will be disabled, which
makes sense, since it wouldn't work anyway.
Adds this feature to checkbox, and ports raised button, flat button, and
radio buttons to this new model.
Adds a checkbox to card_collection that can be disabled.
Hide a (basically bogus) hint from the (soon to be disabled) strong hint
mode in the analyzer that this reveals.
Also, fix warnings in rendering/sector_layout.dart
Also, fix hit testing in rendering/sector_layout.dart
Also, add WidgetToRenderBoxAdapter
Also, make the rendering library debugging tools more resilient to
dumping stuff before layout is complete.
This still leaves Flex and FlexDirection available. At some point once
people have transitioned to Row/Column we should rename Flex to _Flex
and stop reexporting FlexDirection from basic.dart.
Similar to widgets.dart, rendering.dart exports the entire rendering layer.
Also, update the examples to use rendering.dart and widgets.dart. Also clean up
some exports so that the examples have more sensible imports.
Some files are moved by this:
Copy framework/node.dart into types/ - preparing for framework/'s decomissioning.
Move app/scheduler.dart into sky/scheduler.dart - "app" doesn't really make sense.
As part of the SkyBinding cleanup, I made the hit-testing less
RenderBox-specific, by having the HitTestEntry.target member be a
HitTestTarget, which is an interface with the handleEvent() function,
which is then implemented by RenderBox. In theory, someone could now
extend hit testing from the RenderBox world into their own tree of
nodes, and take part in all the same dispatch logic automatically.
This involved moving all the hit testing type definitions into a new
sky/hittest.dart file.
Renamed SkyBinding._app to SkyBinding._instance for clarity.
Moved code around in SkyBinding so that related things are together.
Made WidgetSkyBinding use the existing SkyBinding.instance singleton
logic rather than having its own copy.
I also added some stub README.md files that describe dependencies.

Move app/view.dart to rendering/sky_binding.dart since it's part of the RenderObject API, really (it knows about RenderView intimately).
The tests pass. I didn't check every last example.

This also moves the test for stocks into a new tests/examples/
directory, where we can put tests that test the examples.

The underlying problem is that we lacked a RenderObjectWrapper for the
RenderView, which meant we couldn't handle changing the RenderObject that was
the root of the RenderView. This CL introduces a RenderViewWrapper and uses it
in a new AppContainer widget root. This change allows us to make App a
non-magical Component that is inserted into the AppContainer in the newly
introduced runApp function.
