/**
* @summary SearchHighlight
* @description Search term highlighter for DataTables
* @version 1.1.0
* @author SpryMedia Ltd
*
* License MIT - http://datatables.net/license/mit
*
* This feature plug-in for DataTables will highlight search terms in the
* DataTable as they are entered into the main search input element, or via the
* `search()` API method.
*
* It depends upon the jQuery Highlight plug-in by Bartek Szopka:
* http://bartaz.github.io/sandbox.js/jquery.highlight.js
*
* Search highlighting in DataTables can be enabled by:
*
* * Adding the class `searchHighlight` to the HTML table
* * Setting the `searchHighlight` parameter in the DataTables initialisation to
* be true
* * Setting the `searchHighlight` parameter to be true in the DataTables
* defaults (thus causing all tables to have this feature) - i.e.
* `DataTable.defaults.searchHighlight = true`.
*
* For more detailed information please see:
* http://datatables.net/blog/2014-10-22
