* Sorts a column containing chapter numbers. This can be most useful when

* default, five sections are supported (a.b.c.d.e) with each being upto
* four-digits long. Those defaults are controlled by constMaxSections and
* constMaxSectionDigits respectively, and can be easily changed
*
* @name chapter
* @summary Sort book chapters numerically
