[TB] Allow developers to print out dependency graph

[aaronreed708]

Problem/Concern

Discussed by @smithbk during his SDK educational session this week. It might be a good idea to create a way for developers to print out the dependency graph that the SDK maintains. This could be helpful in debugging issues where a CSS variable or atomic element isn't properly updating and reflecting changes that have been made upstream. An example of this might be the button field in the default theme not transitioning from disabled to enabled when the primary color is initialized. This ability should only be available during development, probably. Maybe through an environment variable? Should this be triggered by an API?

So this issue entails:

• [ ] determine most useful way to display this information for developers
• [ ] determine best way to trigger the action
• [ ] implement solution
