/**
* @summary SlidingChild
* @description Show / Hide row child plugin
* @version 2.1.0
* @author [Nick Adkinson](https://github.com/data-handler)
* @copyright Copyright 2018 Nick Adkinson
*
* This feature plug-in provides functionality for showing and hiding row child
* information in DataTables. This can be particularly useful for displaying
* hierarchical data as a drill-down, or where you wish to convey more information
* about a row than there is space for in the host table.
*
* @example
* $('#myTable').DataTable({
* slidingChild: {
* source: function(parent, response) {
* $.get('/Child/GetByParentId/' + parent.data('id'), response);
* }
* }
* });
*
