Get generic type

GenericType.swift

struct Stack <Element> {
    let values: [Element]

    var elementType: Any {
        get {
            return Element.self
        }
    }
}

let intStack = Stack<Int>(values: [1, 2, 3])
print(intStack.elementType)

let vcStack = Stack<UIViewController>(values:[UIViewController()])
print(vcStack.elementType)

@eyeplum 想取的不是 values 的泛型类型，而是 Stack 的泛型类型。可能这个栗子有点歧义……
