View controller loader

viewControllerLoader.m

//convenient method when working with nibs.. 
//should be used within a view controller subclass
//name your nib the same as your view controller class name 
//this will load it given it's in the main bundle, and
//it will append a child to the view in context (inView:)
//if view is nil, obviously it will not add a subview
//but the view controller will still be added as a child.
//did not bother to implement as a UIViewController category,
//minor error testing but worked without issue for my intended use.

//newly created view controllers view frame gets changed to the view
//in context, in case of use with container view controllers
