// Given an interface (IFactory<> in this example), find everything that
// implements the interface and put it in a map.
//
// Usage:
// public interface IFactory<T> { ... }
// public class AppleFactory : IFactory<Apple> { ... }
// public class BananaFactory : IFactory<Banana> { ... }
// public class ChocolateFactory : IFactory<Chocolate> { ... }
//
// var m = new FactoryManager();   // Automatically scans this assembly for suitable implementations

"Everyone thinks they’re writing the most performance-critical code
  in the world, but in reality maybe one in twenty programmers are
  writing code where anything short of the most egregious bloat and
  carelessness will affect the performance of the system overall.
  Unfortunately, egregious bloat and carelessness are quite common."
