/**
* This plug-in allows sorting of human readable time delta, viz.,
* "1 week", "2 weeks 3 days", "4 weeks 5 days 6hours", etc.
*
* Curently this plugin supports time range from microseconds to decades.
*
* The plugin also takes care of singular and plural values lik week(s)
*
* @name Natural Time Delta
* @summary Sort human readable time delta
*
* @example
* $("#example").DataTable({
* columnDefs: [
* { "type": "natural-time-delta", "targets": 2 }
