ContainerViewController

A trully custom container view controller written in Swift 3.0.1. The view of this object is fully resizable and works great with layout constraints.

Todo

• Mimic UINavigationController without any bar APIs
• More flexible delegate methods
• Simple non-interactive transition
• Interactive transition

Vectors

• A vector contains at least one type.
• vector T - is a list of type T of an arbitrary length, such as T₁, T₂, ...
• vector(n) T - is a list with the length of maximal n T's, such as T₁, T₂, ... , T_n

// vectorized tuple with arbitrary length (like an existetial that can accept a tuple of type `T` of any length)
var t1: (vector Int) = (1, 2)
t1 = (1, 2, 3)
