/**
A base class for Resize, providing:
* Basic Lifecycle (initializer, renderUI, bindUI, syncUI, destructor)
* Applies drag handles to an element to make it resizable
* Here is the list of valid resize handles:
`[ 't', 'tr', 'r', 'br', 'b', 'bl', 'l', 'tl' ]`. You can
read this list as top, top-right, right, bottom-right, bottom,
bottom-left, left, top-left.
* The drag handles are inserted into the element and positioned
absolute. Some elements, such as a textarea or image, don't support
children. To overcome that, set wrap:true in your config and the
element willbe wrapped for you automatically.
Quick Example:
var instance = new Y.Resize({
node: '#resize1',
preserveRatio: true,
wrap: true,
maxHeight: 170,
maxWidth: 400,
handles: 't, tr, r, br, b, bl, l, tl'
});
