  Specifies that an injector should retrieve a dependency from any injector until reaching the
  closest host.
  
  ## Example
  
  ```
  class Dependency {
  }
  
  class NeedsDependency {
    constructor(public @Host() dependency:Dependency) {}
  }
  
  var parent = Injector.resolveAndCreate([
    bind(Dependency).toClass(HostDependency)
  ]);
  var child = parent.resolveAndCreateChild([]);
  var grandChild = child.resolveAndCreateChild([NeedsDependency, Depedency]);
  var nd = grandChild.get(NeedsDependency);
  expect(nd.dependency).toBeAnInstanceOf(HostDependency);
  ```
