Create demo project card repository.

[e-lo]

As part of our effort to create a node registry which would reside within a project card registry, please create an example repository on github which we could use for testing and demonstration purposes.

Repo Settings:

• Travis CI
• Make the repository a template
• Add me (E) as a collaborator
• Create a staging and sandbox branches
• Make master a protected branch requiring PR reviews and required status checks and make "include administrators" for the checks

Repo Contents:

• node_registry.csv with columns node,project
• registry_config.yml with the contents start_node_number: 1000
• projects directory with a project card that adds a few nodes (1000).
• test_projects.py with a test that reads the node additions from project cards, checks for conflicts, and outputs an updated node_registry.csv with a list of all used nodes in the projects.
• travis.yml which installs and runs pytest
• README.md
• LICENSE: either ODC-BY or CC-BY

Note:

• I'd like to make this able to operate independent of the base network by using the start_node_number but a future enhancement would be to feed in the base network as well;

@kulshresthaa: start here once you get going on the broad problem.

@e-lo: This is ready for your review here. I deviated a bit from your spec, using GitHub Actions rather than Travis.
