 * A reference counted box sitting on top of an SObject.

 * When creating an SBox use the s_box_new() macro, it expands to the correct

 * constructor using the C11 _Generic macro.

 *

 * When freeing the SBox use s_object_free() function. If you depend

 * on reference counting use s_object_unref() to do this.
