HttpHeader (Action Controller core 0.0.41-SNAPSHOT API)

```
@Retention(RUNTIME)
@Target({METHOD,PARAMETER})
public @interface HttpHeader
```
When used on a parameter, maps the HTTP Request header to the parameter, converting the type if necessary. When used on method, maps the return value to the specified HTTP Response header. If the parameter type is Consumer, calling parameter.accept() sets the http header value instead of returning it.
