commit 2d946d03ae58fbbd415c6e52c2d89cf8f017bf08
Author: Jean-Philippe Andre <jp.an...@samsung.com>
Date:   Tue Apr 19 17:43:28 2016 +0900

    Efl.Pack: Rename methods and properties
    
    - Children are now contents
    - Efl.Pack_Layout is now a separate class and
      merges Pack_Engine.
    - Removed dumb class Efl.Pack_Item
    - Updated docs
    - Added pack_ or grid_ prefixes to some methods
