  From this perspective, this tree serves as a proof of concept for abstractions and features which could benefit the framework, but are easier to implement within a DDS initially.
  This tree serves to get these feature into the hands of users much faster than could be done at the framework level.
  +## Recommended Developer Workflow
  +
  +This package can be developed using any of the [regular workflows for working on Fluid Framework](../../../README.md) and/or its Client release group of packages, but for work only touching the tree package, there is an optional workflow that might be more ergonomic:
  +
  +- Open the [.vscode/Tree.code-workspace](.vscode/Tree.code-workspace) in VS Code.
  + This will recommend a test runner extension, which should be installed.
  +- Build the Client release group as normal (for example: `npm i && npm run build:fast` in the repository root).
  +- After editing the tree project, run `npm run build` in its directory.
  +- Run tests using the "Testing" side panel in VS Code, or using the inline `Run | Debug` buttons which should show up above tests in the source:
  + both of these are provided by the mocha testing extension thats recommended by the workspace.
  + Note that this does not build the tests, so always be sure to build first.
  +
  +This package uses [`good-fences`](https://github.com/smikula/good-fences) to manage intra-package dependencies in `fence.json` files.
  +If modifying such dependencies, learn how `good-fences` works, and review (and update if needed) the "Architecture" section below.
