Create a project roadmap

[pavithraes]

Is your feature request related to a problem? Please describe.
New users can benefit from knowing where the project is headed, what that can expect, and where they can potentially contribute.

Describe the solution you'd like
Discuss potential themes, focus areas, and priorities for the next 12-18, and create a roadmap document. We can then create specific issue tracking roadmap items.

Additional context
There is a preliminary list here: https://github.com/Point72/csp/wiki#roadmap

• historical distribution / parallelization to improve runtime
• realtime distribution / cross process communication
• warmup processing ( @ptomecek perhaps you can describe this better than I could )
