New Node Script

[katyhuff]

This issue can be closed when the following capability exists:

A script can be run (e.g. new-node <uid>) which creates a new node directory structure ready for editing.

new-node script development:

• fix template node to minimum viable node (MVN)
  • move example exercises to new examples/ directory
  • retain one exercise in MVN
• add jinja fill-in for UID
• write script to copy and update based on template MVN

[davis68]

What I'm doing for the first step (in branch davis68-new-node):

• copying template-node to template-node-full as a stub for a "maximal" node
• renaming special-relativity-exercise.yml to basic-exercise.yml in template-node

[davis68]

The script now exists in bin/new-node. The directories may need to be updated based on the outcome of the submodule/node location discussion.
