+/**
+ * Sorts a column containing chapter numbers. This can be most useful when
+ * using DataTables for a book or book reference style application. By
+ * 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

+ *       columnDefs: [
+ *         { type: 'chapter', targets: 0 }
+ *       ]
+ *    } );
