Implement 12 cell grid mode to show allow showing more metrics.
Experimental means that this layout will not render properly on every
screen size (though should work on bigger screens well).
That would require more media queries and css logic to tweak the styling
This may be implemented at a later stage.
Remove dependency on metric formatting logic at the server. Implement
the formatting of the raw data on the client side. Make adding
new metric tiles more modular and extensible via simplified creation API
