  /**
   * This plug-in will add automatic detection for currency columns to 
   * DataTables. Note that only $, £ and € symbols are detected with this code,
   * but it is trivial to add more or change the current ones. This is best used
   * in conjunction with the currency sorting plug-in.
   * 
   * 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 Detect data of numeric type with a leading currency symbol.
