This moves input.dart to editing2/, since that way we can define the layering as strictly unidirectional. It also reorders a bunch of imports to fit the style guide. I removed the old remnants of the widgets example, and put the fn2 examples into the examples/widgets/ directory, to parallel the framework directory names.

SKY SDK
Sky and Sky's SDK are designed as layered frameworks, where each layer depends on the ones below it but could be replaced wholesale.
The bottom-most layer is the Sky Platform, which is exposed to Dart
code as the dart:sky package.
Above this are the files in the painting/ directory, which provide APIs related to drawing graphics.
Layout primitives are provided in the next layer, found in the
rendering/ directory. They use dart:sky and the
APIs exposed in painting/ to provide a retained-mode layout and
rendering model for applications or documents.
Widgets are provided by the files in the widgets/ directory, using a reactive framework.
Text input widgets are layered on this mechanism and can be found in the editing2/ directory.
