Add a section to the Developer's Guide to include an HLM-FATES API design document and standards/guidelines #54
Description
Is your feature request related to a problem? Please describe.
As we work to refactor the API over time, we should incorporate some documentation to define the design principles and guidelines.
Describe the solution you'd like
A single section with a design document should suffice.
Describe alternatives you've considered
We could explain the design outline in interface modules in the various HLMs, but I think it'd be better to have a single location describing the overall goal and any HLM-specific requirements to provide ease of maintenance.
