Dynamic composition interface

[coordt]

Is your feature request related to a problem? Please describe.

I want to be able to see how the context flows through the layers of a composition without generating the project.

Describe the solution you'd like.

Provided a composition via a file or stdin, show questions/labels at each overlay and how the context changes.

Optionally, you can use a set of provided answers to see how the context is rendered.

The default output should be a YAML, JSON, or TOML format data structure.

Human-friendly outputs should also be available.

Describe alternatives you've considered
