Auto-generate separate documents for each level

Nobody has claimed this yet.

One of my long-term goals is to build a collaborative editing tool that facilitates building and maintaining education standards. You can see an early attempt at [Open Competencies](http://opencompetencies.org). Until that tool is more polished, it might be beneficial to write a quick script that parses the main cs_standards.md file, and automatically generates smaller documents for the individual focus areas, and perhaps for each competency area as well. It's an easy script to write, and may be easier to work with.

Must make it clear no one should spend time manually editing those documents.

Start with cs_standards.md and inspect the repository's current document structure to determine the focus-area and competency-area boundaries. Build a script that generates the smaller documents and clearly marks them as generated rather than manually editable; done means the documents can be regenerated consistently from the main file.
