Add the ability to use either with Java 8

[k33g]

It could be interesting to use golo as library for Java:

import gololang.error.Result;
import java.util.function.Function;
...

Function<String, Result<Integer, RuntimeException>> toInt = (String val) -> {
  try {
    return Result.ok(Integer.parseInt(val));
  } catch (Exception e) {
    return Result.fail("Huston? We've got a problem!");
  }
};

Integer result = toInt.apply("fourty-two").either(value -> {
  System.out.println("Success: " + value);
  return value;
}, err -> {
  System.out.println(err.getMessage());
  return 42;
});

What's the link between your Java 8 code sample and using Golo as a library?

I understand what you have in your commit, but I can't see your point in the discussion 😉 🍷

Java 8 brings us Optional, but not Result. I found it interesting to use
the Result of Golo, and especially the either method directly with Java.
But, to my mind the version of either with FunctionReference is hard to
use
And it's more "human" readable if we can pass Function as parameters of
either (the code becomes beautiful as JavaScript :p)

It's also an other way to demonstrate the interoperability between Golo and
Java, and by the way, it shows that Golo has some assets that not exist in
Java.

... Even if Result is written in Java
