Detailed Description

Bin is a Container with a single child.

Bin maintains a reducible border around a single child in a designated area of the allocated space. The reducible border is specified by the set_reducible function. The area outside the reducible boarder is set by set_reserved and remains fixed. The size are allocated in the order of precedence:

reserved > minimum of child > natural of child > reducible

The minimum size of the Bin is the reserved + minimum of child. The natural size is reserved + natural of child + reducible.
