We're trying to follow the pattern described in https://www.dartlang.org/tools/pub/package-layout.html

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.

Also, move a widget example from examples/raw/ to examples/widgets/

Create an example app that demonstrates interactive coordination of an fn tree and a raw RenderObject tree.

Sector changes:
- implement the intrinsic sizing box API on RenderBoxToRenderSectorAdapter
- remove some debug print statements
- fix getIntrinsicDimensions() on RenderSolidColor to return true values
- factor out the default demo

RenderObject changes:
- BoxConstraints.isInfinite() now returns true only if both dimensions are infinite

fn changes:
- implement UINodeToRenderBoxAdapter
- rename RenderObjectToUINodeAdapter to RenderBoxToUINodeAdapter

Tests:
- add a test for sector layout
- make TestRenderView support being run without the unit test framework

We need the key to be a String even though we claimed we could support any
Object. Also, clean up some style nits including shortening the |root| getters
on OneChildRenderNodeWrappers.

Fixes https://github.com/domokit/sky_sdk/issues/26.

FlexExpandingChild -> Flexible
StackPositionedChild -> Positioned

Also, name the child argument |child| for consistency.

This CL moves the bulk of the SkyView code out of the |framework| directory
because the |framework| directory was redundant in Dart package import
declarations.

Although the basic widgets are wrappers, that's an implementation detail and
shouldn't be encoded in the name of the library.

Verify that callers correctly set parentUsesSize if they use the child's size (and fix a few cases that didn't).
This introduces a bunch of code that should only run in debug builds, but we don't have #ifdefs yet.

Make it easier to debug examples/widgets/container.dart, since it is currently showing a crazy clipping/transform bug.

Make Material actually create material, with opinions about what that
means.

Make FloatingActionButton use this.

Make Scrollable use this.

Make BoxDecoration support drawing a circle instead of a rectangle, so
that floating action button doesn't need a custom painter.

Implement RaisedButton (and remove button.dart, since there's no
"button" in Material Design).

Make InkWell have a "child" argument instead of "children", and not
have it introduce a Flex into the hierarchy.

Update container.dart example. Clean up some imports.

Also:
 - Make RenderProxyBox non-abstract
 - Upgrade the old container.dart example
 - Minor fixes to ui_mode.dart to make this work
