> In 3.2 VertexPrograms like {{PageRankVertexProgram}} will have a dedicated step that allows to do things like {{g.V().out().out().pageRank()}}. Would be nice to have a general step {{program()}}, so that we can do the same thing with any {{VertexProgam}}, e.g.
> {code}
> // pre-calculate "users who bought this, also bought" and create uwbt-edges for the top 100 results per vertex
> g.V().as("a").in("bought").out("bought").where(neq("a")).as("b").select("a","b").
>   program(CollaborativeFilterVertexProgram.build().source("a").target("b").limit(100).edgeLabel("uwbt").weightProperty("weight").create())
> {code}
