Aggregate properties across a jquery collection

This plugin is used to normalize or aggregate a certain property across a jquery element collection, with
optional grouping into rows when normalizing. Normalization is useful for arranging floated elements of differing heights into even rows.

Examples

Find the maximum height out of a group of elements:

$('.elements').aggregate('height', 'max');

Make all elements in a collection the same height as the highest:

$('.elements').normalize();

Make a group of elements all the same height as the highest, in rows of 4 elements each, with bottom-aligned content:

$('.elements').normalize({
    property: 'height',
    type: 'max',
    per_row: 4,
    callback: function(el, val) {
        el.css('paddingTop', val - el.height() + 'px');
    }
});

Make a group of elements all the same height as the highest, arranged in rows of a specified pixel width:

var width = $('.wrapper').width();
$('.wrapper > .element').normalize({
    property: 'height',
    type: 'max',
    per_row: width + 'px'
});
