/**
* @defgroup Box Box
*
* A box object arranges objects in a single row within a box. Sub objects can
* be added at the start, end or before or after any existing object in the
* box already. It can have its orientation changed too. How a child object is
* sized and otherwise arranged within the box depends on evas hints.
* evas_object_size_hint_align_set() will set either the alignment within its
* region if the region allocated is bigger than the object size. If you want
* the sub object sized up to fill the allocated region, use -1.0 for the
* apporpriate horizontal or vertical axes. evas_object_size_hint_weight_set()
* will set the packing weight. The weights of all items being packed are added
* up and if items are to be sized up to fit, those with the higher weights get
* proportionally more space.
*
* NOTE: Objects should not be added to box objects using _add() calls.
