UIView with NIB loading and Auto Layout by Example

Added a couple repos to GitHub: Auto Layout by Example — an Xcode project that includes several views laid out via Auto Layout to demonstrate how to achieve some commonly sought after results.

UIView+LENibLoading — A category on UIView and an accompanying subclass of UIView for loading views from a nib.

Auto Layout has its quirks but it is definitely going to be a big part of our future as iOS developers so the easier we can make its use and the more familiar we get with it the better. With the likelihood of a new iPhone coming out with vastly different screen dimensions, hopefully this helps some people get going sooner than later :)
