> Gelly contains a set of {{MapFunction}} between {{Vertex}} and {{Tuple2}} and between
{{Edge}} and {{Tuple3}}. A {{Vertex}} is a {{Tuple2}} and an {{Edge}} is a {{Tuple3}}, and
conversion in the opposite direction can be performed with a single object per {{MapFunction}}.
> This only applies to the Gelly Java API. Scala tuples are not related to {{Vertex}} or
{{Edge}}.
