    Hi @jorgebay,
    The purpose of the translator is to allow building of a script from bytecode for users
that don't yet have bytecode implementation on their Gremlin Server but want to use GLV instructions
rather than writing scripts in text. 
    Case in point, I'll be using the project on Azure CosmoDB but I cannot send bytecode as
it's not yet supported, they're working on it. So I don't want to have to write all my queries
as strings and then have to go back at a later date and convert to glv steps. I'd rather use
the glv steps and go back later and implement terminal commands. This might just be my own
personal preferences, but I'm sure others would appreciate that flexibility?
    This is how it would be used:
    const g = new graph.Graph().traversal();
    g.V().order().by('age', t.order.decr);
    const script = new Translator('g').translate(g.getBytecode());
    That script could then be submitted via the client.
