Name
====
dimensionsMinMax(whnx) - jQuery plug-in to get min & max width & height
Parameters
==========
whnx - A 4-element array to receive the min and max values of the elements:
whnx[0] = minimum width;
whnx[1] = maximum width;
whnx[2] = minimum height;
whnx[3] = maximum height.
Returns
=======
this - so it can be "chained".
Example
=======
var minmax = new Array(4);
var number_of_images = $('img').dimensionsMinMax(minmax).class('abc').length;
console.log('number of images = ', number_of_images);
console.log('width range = ', minmax[0], ' to ', minmax[1]);
console.log('height range = ', minmax[2], ' to ', minmax[3]);
