+ * It can sometimes be useful to get the average of data in an API result set,
+ * be it from a column, or a collection of cells. This method provides exactly
+ * that ability.
+ *
+ *  @name average()
+ *  @summary Average the values in a data set.
+ *  @author [Allan Jardine](http://sprymedia.co.uk)
+ *  @requires DataTables 1.10+
+ *
+ * @returns {Number} Calculated average
+ *
+ *  @example
+ *    // Average a column
+ *    var table = $('#example').DataTable();
+ *    table.column( 3 ).data().average();
+ *
+ *  @example
+ *    // Average two cells
+ *    var table = $('#example').DataTable();
+ *    table.cells( 0, [3,4] ).data().average();
