refactor: Major simplification in providing implementation types (#2)

This PR is an effort to address #1. It removes all boilerplate
  from individual implementation files, and moves it into
  a small, fixed section in the single `all.ts` module for each
  type that collects up all of the implementations relating
  to that type.
