/**
* This plug-in will provide numeric sorting for currency columns (either
* detected automatically with the currency type detection plug-in or set
* manually) while taking account of the currency symbol ($ or £ by default).
*
* DataTables 1.10+ has currency sorting abilities built-in and will be
* automatically detected. As such this plug-in is marked as deprecated, but
* might be useful when working with old versions of DataTables.
*
* @name Currency
* @summary Sort data numerically when it has a leading currency symbol.
* @deprecated
* @author [Allan Jardine](http://sprymedia.co.uk)

* @example
* $('#example').dataTable( {
* columnDefs: [
* { type: 'currency', targets: 0 }
* ]
