Promoting collaboration

[Tokazama]

It would be nice if more people could participate in development here, even if it was just reviewing PRs. Obviously we need documentation and examples to help people understand the scope of package, but we also have some things we've gravitated towards that aren't covered in ColProc.

I've come to think of these sorts of things before adding it here.

• Additions should typically only be dependent on trait types. This forces us to create an interface that is generic and robust to all the different array types we test.
• Would it make sense to eventually include this in base Julia or the standard library? Or would it be more suited as a package?

Thoughts?
