jQuery^: JavaScript Language Library

JQuery is an open source MIT license library that provides several very needed improvments to browser based Javascript:

1. It makes working with document object model elements very easy
2. It makes all the browsers act the same, within the functions it provides. (this is no small feat)
3. Provides a modular plug in system for extending the library.
