Description

Both SplitApplyCombine.jl and DataFrames.jl export flatten. I would add it to DataAPI.jl. The question is what docstring it should have? Maybe something like:

Flatten collection of collections into a single collection

Is enough?

@andyferris - after this is established maybe you could add DataAPI.jl to SplitApplyCombine.jl as a dependency and make innerjoin and flatten implement this interface? Then SplitApplyCombine.jl and DataFrames.jl could be used together more easily.

Research direction

Start by comparing how SplitApplyCombine.jl and DataFrames.jl currently export and document flatten, then inspect DataAPI.jl's existing namespace conventions. Done requires resolving the docstring and interface design, adding flatten to DataAPI.jl, and determining whether the suggested SplitApplyCombine.jl dependency changes belong in this issue.
