List mongodb collections in descending order of size. Helpful for finding largest collections. First number is "size," second is "storageSize."

	var collectionNames = db.getCollectionNames(), stats = [];
	collectionNames.forEach(function (n) { stats.push(db[n].stats()); });
	stats = stats.sort(function(a, b) { return b['size'] - a['size']; });
	for (var c in stats) { print(stats[c]['ns'] + ": " + stats[c]['size'] + " (" + stats[c]['storageSize'] + ")"); }
