[WIP] Things that still need doing

[TylorS]

The list on #1 is a bit more difficult to look at now this is a continuation of where effort still needs to be placed.

• [ ] documentation generation ( markdox? : custom? )
  • [ ] Document external API
  • [ ] Document core thoroughly
  • [ ] Document monorepo workflow and processes
  • [ ] Start a 'help wanted' section for operators currenty not implemented (xstream extras etc)
• [ ] Investigate how to properly do operator fusion with things happening across packages
• [ ] Add performance tests
• [ ] Lots of duplicate dependencies are added - investigate keeping things more DRY (this will speed up travis testing) - Maybe builder is still useful for this
• [ ] Build package with fluent API - how well does TypeScript handle this - name? (@tempest/main, @tempest/fluent) - should I look into getting the "tempest" package name
• [ ] Build Cycle.js adapter and run() packages
