/**
 * Sorts columns by any number, ignoring text. This plugin is useful if you have
 * mixed content in a column, but still want to sort by numbers. Any number means
 *
 *  - integers, like 42
 *  - decimal numbers, like 42.42 / 42,42
 *  - signed numbers, like -42.42 / +42.42
 *  - scientific numbers, like 42.42e+10
 *  - illegal numbers, like 042, which is considered as 42,
 *  - currency numbers, like €42,00
 *
 * Plain text is ignored; columns with no recognizable numerical content
 * is pushed to the bottom of the table, both ascending and descending.
 *
 *  @demo http://jsfiddle.net/vkkL5tv7/
 *
 *  @name Any number
 *  @summary Sort column with mixed numerical content by number

 *  @example

 *       columnDefs: [
 *         { type: 'any-number', targets : 0 }
 *       ]
 *    } );
