/**
* When dealing with computer file sizes, it is common to append a post fix
* such as KB, MB or GB to a string in order to easily denote the order of
* magnitude of the file size. This plug-in allows sorting to take these
* indicates of size into account. A counterpart type detection plug-in
* is also available.
*
* @name File size
* @summary Sort abbreviated file sizes correctly (8MB, 4KB etc)

* $('#example').dataTable( {
* columnDefs: [
* { type: 'file-size', targets: 0 }
* ]
