Support Javascript Typed Arrays about crypto-js

[GoogleCodeExporter]

To do that, I would probably extend WordArray to create a new TypedWordArray 
type that we could customize. And I'd probably keep that definition in a 
separate component file rather than in the core since it wouldn't be 
cross-browser.

In fact, since JavaScript is loosely typed, you should be able to pass 
WordArray a typed array, and it would just use it and continue on as normal. 
You may run into problems, however, when the library tries to use the standard 
array methods, such as push, slice and splice. Something to keep in mind if you 
decide to toy with the idea.

I like the second idea of just having WordArray be able to accept an 
ArrayBuffer.  That seems like the most natural fit for users of the library.

However, my thinking was to actually extract the data out of the ArrayBuffer, 
into the WordArray words member.  Since this member is accessed directly in the 
library, this seems like the only real option without significant surgery.

Doing the ArrayBuffer <-> WordArray.words conversions won't be particularly 
fast, but they'll at least be convenient for users of the service.

Thoughts?

The latest release includes the ability to create WordArrays from typed arrays. 
You'll need to include an additional component -- lib-typedarrays.

<script 
src="http://crypto-js.googlecode.com/svn/tags/3.1/build/components/core.js"></sc
ript>
<script 
src="http://crypto-js.googlecode.com/svn/tags/3.1/build/components/lib-typedarra
ys.js"></script>
<script>
    var wordArray = CryptoJS.lib.WordArray.create(uint8View);
</script>

You can create a WordArray from any of the typed array views -- Int8Array, 
Int16Array, etc. -- or from an ArrayBuffer, or from a DataView.
