/*! Parser: metric */

* Demo: http://jsfiddle.net/Mottie/abkNM/382/

* Set the metric name in the header (defaults to 'm|meter'), e.g.
|
|
* <th data-metric-name-abbr="b|B" data-metric-name-full="byte|Byte|BYTE">HDD Size</th>
|
|
* <th data-metric-name="m|meter">Distance</th> <!-- data-metric-name is deprecated in v2.22.2 -->
