Add documentation on the new integrations framework.
Review Request #7948 — Created Feb. 6, 2016 and submitted — Latest diff uploaded
This includes guides on how to consume the integrations framework in a project, and how to write new integrations. The guide on consuming the integrations framework walks developers through the classes they need to create, settings to set, and other responsibilities for the consuming application. The guide on writing integrations covers how to build an integration, manage configuration, and more. This also sets up the codebase docs for the integrations module.
Built and read through the docs, checking for links and typos.
