/**
* Although DataTables' internal numeric sorting works no problem on negative
* numbers, it does not accept positively signed numbers. This plug-in will
* sort just such data numerically.
*
* @name Fully signed numbers sorting
* @summary Sort data numerically with a leading `+` symbol (as well as `-`).
* @author [Allan Jardine](http://sprymedia.co.uk)

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