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

	function getReadableFileSizeString(fileSizeInBytes) {

	var i = -1;
	var byteUnits = [' kB', ' MB', ' GB', ' TB', 'PB', 'EB', 'ZB', 'YB'];
	do {
	fileSizeInBytes = fileSizeInBytes / 1024;
	i++;
	} while (fileSizeInBytes > 1024);

	return Math.max(fileSizeInBytes, 0.1).toFixed(1) + byteUnits[i];
