Scala extensions for Google Guice

Features:

• Manifest[T] -> TypeLiteral[T] conversion (typeLiteral[T])
• Binding DSL extensions using type parameters to specify types
• ScalaModule trait including the above binding DSL extensions

  class MyModule extends AbstractModule with ScalaModule {
	def configure {
	  bind[Service].to[ServiceImpl].in[Singleton]
	  bind[CreditCardPaymentService]
	  bind[Bar[Foo]].to[FooBarImpl]
	  bind[PaymentService].to[CreditCardPaymentService]
	}
  }

Future:

• TypeLiteral[T] -> Manifest[T] conversion
• Have Manifest[T] injected anywhere Guice could inject TypeLiteral[T] (see Jesse's post for context)
• Extractor objects for pattern-matching against the binding AST

If technically possible:

• Inject Option[T] for optional dependencies
• Injection that takes variance into account
