/**
|
|
* This plug-in for DataTables represents the ultimate option in extensibility
|
|
* for sorting date / time strings correctly. It uses
|
|
* [luxon](https://moment.github.io/luxon/) to create automatic type detection and
|
|
* sorting plug-ins for DataTables based on a given format. This way, DataTables
|
|
* will automatically detect your temporal information and sort it correctly.
|
|
*
|
|
* For usage instructions, please see the DataTables blog
|
|
* post that [introduces it](//datatables.net/blog/2014-12-18).
