Milestone GMOC: S2.a Spiral 2 prototyping plans

Complete Spiral 2 Prototyping Plans. Document plans for gathering and sharing operational data with Spiral 2 control framework projects, and with several exemplar projects that cover different types of aggregate data. Initial plans will include at least 1) going over the Common Operational Dataset document, and developing a plan to gather as much of this data as each project can produce, in the format of their choosing, 2) going over the Operational Data Format and developing a plan to collect any data projects can produce in that format.
