/*!
 * PerfectMasonry extension for Isotope
 *
 * Does similar things as the Isotopes "masonry" layoutmode, except that this one will actually go back and plug the holes
 * left by bigger elements, thus making a perfect brick wall. Profit!
 * 
 * Usage:
 * 	$('#grid').isotope({
 * 		layoutMode: 'perfectMasonry',
 *		perfectMasonry: {
 *			layout: 'horizontal',		// Set layout as vertical/horizontal (default: vertical)
 *			columnWidth: 200,			// Set/Prefer columns to x wide (default: width of first tile)
 *			rowHeight: 200,				// Set/Prefer rows to y high (default: height of first tile)
 * 
 *			liquid: true,				// Set layout as liquid (default: false)
 *			cols: 3,					// Force to have x columns (default: null)
 *			rows: 3,					// Force to have y rows (default: null)
 *			minCols: 3,					// Set min col count (default: 1)
 *			minRows: 3,					// Set min row count (default: 1)
 *			maxCols: 5,					// Set max col count (default: 9999)
 *			maxRows: 4					// Set max row count (default: 9999)
 * 		}
 * 	});
