/**
* Fairly simply, this plug-in will take the data from an API result set
* and sum it, returning the summed value. The data can come from any data
* source, including column data, cells or rows.
*
* Note that it will attempt to 'deformat' any string based data that is passed
* into it - i.e. it will strip any non-numeric characters in order to make a
* best effort attempt to sum all data types. This can be useful when working
* with formatting numbers such as currency. However the trade-off is that no
* error is thrown if non-numeric data is passed in. You should be aware of this
* in case unexpected values are returned - likely the input data is not what is
* expected.
*
* @name sum()
* @summary Sum the values in a data set.
* @author [Allan Jardine](http://sprymedia.co.uk)
* @requires DataTables 1.10+
*
* @returns {Number} Summed value
*
* @example
* // Simply get the sum of a column
* var table = $('#example').DataTable();
* table.column( 3 ).data().sum();
*
* @example
* // Insert the sum of a column into the columns footer, for the visible
* // data on each draw
* $('#example').DataTable( {
* drawCallback: function () {
* var api = this.api();
* api.table().footer().to$().html(
* api.column( 4, {page:'current'} ).data().sum()
* );
