Expose more Grid configuration

[WoozyG]

This component is especially helpful when selecting from a large list of items with discrete attributes. It would be even better if the left grid was exposed in such a way that we could easily add a header row for filter controls, to allow users to filter items by relevant values. I'd be happy with a standard text filter per column, but allowing customizing would be nice.

Since the grids are final and private, I would have to modify the source or modify the class at runtime to get at the grid to call addHeaderRow().

Thanks for sharing the feedback! .. version 2.0.1 should be already available with your proposed change. Please tell us if you find problems by using it.

Except I failed to mention we are on Vaadin 8 LTS, and can't use the 2.0+ releases :(

I also failed to flag this so I didn't get notified, or I would have provided feedback sooner.
