function inject(tokens: any[], fn: Function): () => any;
  Description
Allows injecting dependencies in beforeEach() and it().
Example:
beforeEach(inject([Dependency, AClass], (dep, object) => {
  // some code that uses `dep` and `object`
  // ...
}));
it('...', inject([AClass], (object) => {
  object.doSomething();
  expect(...);
})
  Notes:
- inject is currently a function because of some Traceur limitation the syntax should eventually becomes 
it('...', @Inject (object: AClass, async: AsyncTestCompleter) => { ... });
