/**
 * A more robust 'typeof'.
 * https://gist.github.com/wizard04wsu/8055356
 * 
 * 
 * For each of the type testing methods, the only parameter is the item to be tested. These methods do not perform coercion.
 * 
 * is(o) - Returns the item's type.
 *       - NaN is considered its own type (instead of a number), since it essentially represents something that cannot be converted to a number.
 *       - For objects, the type of the object is given instead of just 'object' (e.g., 'Array').

Libraries

• jQuery - The de-facto library for the modern age. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.
• Backbone - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.
• AngularJS - Conventions based MVC framework for HTML5 apps.
• Underscore - Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.
• lawnchair - Key/value store adapter for indexdb, localStorage

Libraries

• 960 Grid System - An effort to streamline web development workflow by providing commonly used dimensions, based on a width of 960 pixels. There are two variants: 12 and 16 columns, which can be used separately or in tandem.
• Compass - Open source CSS Authoring Framework.
• Bootstrap - Sleek, intuitive, and powerful mobile first front-end framework for faster and easier web development.
• Font Awesome - The iconic font designed for Bootstrap.
• Zurb Foundation - Framework for writing responsive web sites.
• SASS - CSS extension language which allows variables, mixins and rules nesting.
• Skeleton - Boilerplate for responsive, mobile-friendly development.
