1/**
2 * This plug-in for DataTables represents the ultimate option in extensibility
3 * for sorting date / time strings correctly. It uses
4 * [Moment.js](http://momentjs.com) to create automatic type detection and
5 * sorting plug-ins for DataTables based on a given format. This way, DataTables
6 * will automatically detect your temporal information and sort it correctly.
7 *
8 * For usage instructions, please see the DataTables blog
9 * post that [introduces it](//datatables.net/blog/2014-12-18).
