Columns resizing

[nick-keller]

API

A resazableColumn: boolean prop

Behavior

• Column start off as they do today, respecting their given width, maxWidth, minWidth
• Once resized, a column becomes of fixed-width (width: '0 0 <width>px', and no min and max-width)

Questions

• How should other columns react when a column is being resized? Should they adjust in real-time or become fixed temporarily?
• The parent should handle the width change, but how would the API look like? onColumnWidthChange prop?
