## Usage

```
window.onload = function() {
    var contain = new ContainElement({
        id: 'element', // the id of the element to be contained
        width: '100', // (optional) element width in pixels (unset: element width)
        height: '100', // (optional) element height in pixels (unset: element height)
        valign: 'top', // (optional) vertical alignment: top|bottom (unset: middle)
        halign: 'left' // (optional) horizontal alignment: left|right (unset: middle)
    });

    // (example) update the size and positioning on window resize
