Fix #28

[cescoffier]

Add support for enum in results

[vietj]

just looking at it, it seems that we don't handle the case with an enum annotated with @VertxGen. So we need to support it too.

[cescoffier]

You mean something like this:

@VertxGen
public enum SomeVertxEnum {
  FOO, BAR, WIBBLE
}

This does not change anything (it is handled as an enum).

[cescoffier]

Actually, it does not generate anything for such enum.

[cescoffier]

I've added a unit test with an enum annotated with @VertxGen.

looks good to me
