Can grid markup default to the theme settings?

[brucewyne]

The idea behind using our own "grid framework" was to be agnostic about the theme we use. That said, it'd be nicer to conform to what the theme is using.

The idea would be that we could do something like:

<?=$grid->openContainer()?>`
    <?=$grid->openColumn(4)?> 
        <div class="product-image">
            ....
        </div>
    <?=$grid->closeColumn()?>
    <?=$grid->openColumn(8)?> 
        <div class="product-description">
            ....
        </div>
    <?=$grid->closeColumn()?>
<?=$grid->closeContainer?>

Is this overkill? Or should we just stick with a simple agnostic grid we use now?
