// Works for all types that conform CustomStringConvertible protocol, e.g. Int, Float. 
// Raw value will be converted to string and used as key, e.g.
// 10.localize, will search for "10" key.
// If key not exists, then string value will be returned

//  UIView+Contstraints.swift
//
//  HOW TO USE
//  1. Setup constraints and define NSLayoutConstraint.identifier
//  2. Use identifier as parameter for call
//  3. Call on superview: if let constraint = self.view.constraintByStringId("Id") { } 
//  4. Change, animate or replace constraint
