Currently our bin scripts point to the same root index.ts file that exposes our public API. The implication is that developers cannot import {foo} from "@google-cloud/functions-framework" without spinning up the webserver. This adds some complexity to local development and testing workflows.

I think a reasonable change would be to extract the initialization logic into a separate file (eg main.ts) that spins up the webserver. Then update our bin scripts to point to that file.
