Create a bare module branch

[dakotablair]

Goals:

• Minimal spec.json and display.yaml
• Usable with KB SDK tutorial with minimal effort
  • Experienced users can start with the bare repo.
  • Inexperienced users can run a script to align the module with the existing tutorial.

This issue is almost complete, but the script still fails. The problem arises when a value such as user.name is unset. In that case git config --get user.name will exit with a nonzero status code. Using the trap command should be enough to avoid this problem.
