Right now we have IInjectionPoint that represents an injection point. Also we have a few interfaces which extends IInjectionPoint:
IInjectionPointField - a filed annotated @Inject
IInjectionPointParameter - a parameter of the method annotated @Inject
IInjectionPointMethod - a method annotated @Inject

IInjectionPointFiled and IInjectionPointParameter correctly extend IInjectionPoint since they are injection points. But IInjectionPointMethod is not an injection point. It's an initializer method actually. So let's introduce a new interface IInitializerMethod instead of IInjectionPointMethod. InitializerMethod should not extends IInjectionPoint.
