Grouped Bar bug

[samuelhorwitz]

When I try to use a grouped bar, I run into an issue that seems like it may be due to some recent refactoring bringing grouping code into this repository, from the main one.

Simple reproduction:

groupedbar(repeat(0:5, outer=4),
    [1:5 6:10 11:15 16:20],
    group = repeat(["a", "b", "c", "d"], inner=5),
)

The error I see:

UndefVarError: splittable_kw not defined

When I look around for splittable_kw it appears to be a function that is still referenced but who's definition was lost sometime early April.
