Fullfil protocol requirements explicitly with extensions and types

Introduction

Types implementing protocols with optional features (either through default implementations on extensions, or optional methods on objective-C protocols) do not have a way to detect typos or upstream changes to the protocol will result in behavioral changes. This proposal attempts to rectify that in a manner similar to override on subclassed types.

gen.swift is a direct port of cfdrake's helloevolve.py from Python 2.7 to Swift 3
-------------------- https://gist.github.com/cfdrake/973505 ---------------------
gen.swift implements a genetic algorithm that starts with a base
population of randomly generated strings, iterates over a certain number of
generations while implementing 'natural selection', and prints out the most fit
string.
The parameters of the simulation can be changed by modifying one of the many
