Allow to read parameters from Injection annotations

[GoogleCodeExporter]

 It would be fine if Provider could read passed parameters in Inject
related annotations. Example:

class Foo {
    @Inject(Foo.class.getName()) Logger logger;

}

So in Module.configure(Binder binder) I would have:

Porivder pp = new Porivder() {
Logger get() {
 return Logger.getLogger(getAnnotation(Inject.class).value()); //
getAnnotation(..) would return instance of Inject annotation and I have
made asumption that Inject annotation has value()
 // or maybe?
 return Logger.getLogger(getInstancianisedClass().getName());
// then in Foo class we have simple @Inject Logger logger;
}
}

bind(Logger.class).toProvider(pp).in(SingletonForInstancianisedClass.class);

The same would be used for injecting WebServices:

@Inject @WebService("ClockServiceLocation") IClockService clockService;

So in Module.configure(Binder binder) I would have:

   final Properites prop = new Properties();

prop.load(getClass().getClassLoader().getResourceAsStream("myconfig.properites")
);

Porivder pp2 = new Porivder() {
IClockService get() {
   return new ExampleDynamicClientWebServiceStub(   prop.get(            
getAnnotation(WebService.class).value()                ).toString()        );
}
}

bind(IClockService.class).annotatedWith(WebService.class).toProvider(pp2);

Sorry that this is posted as Defect but was unable to find where to change type 
of issue.

Well in both cases it is not possible to do that in Java (static types checking 
is
too restrict) but concept of:

- <T> T getAnnotation(Class<T> class) in Provider
- SingletonForInstancianisedClass as a Scope
- Class getInstancianisedClass() in Provider

is nice

Duplicate of issue 27. That issue suggests we inject the injection point to 
address this problem.
