MethodInterceptor (avaje inject 8.13-RC3 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface MethodInterceptor
```
Provides method interception such that logic can be provided both before and after method invocation.
MethodInterceptor instances are provided by AspectProvider.interceptor(Method, Annotation).

- Method Summary
  
  All Methods Instance Methods Abstract Methods
  Modifier and Type Method Description
  
  void invoke(Invocation invocation)
  Implementation can perform before and after invocation logic.

- Method Detail
  - invoke
```
void invoke(Invocation invocation)
     throws Throwable
```
    Implementation can perform before and after invocation logic.
    If a method interceptor wants to replace the result it does this via Invocation.result(Object). This is a little different to traditional method interceptors (i.e. org.org.aopalliance.intercept.MethodInterceptor). It is done this way to handle implied generic return types in the generated source code.
    
    Parameters:
    
    invocation - The invocation being intercepted
    
    Throws:
    
    Throwable - If the interception or underlying invocation throws an exception
