js-generator.scala

/*
This is a macro that takes a GQL statement and produces js. I achieve this 
by forking out to node and executing the babelRelayPlugin.  This solution is sub-par for
3 big reasons:

  1) Naming - Since it executes outside the "scope" (aka independently). I have to do some error prone things.
   * use the js.constructorOf[FooClass] and assign it to a global variable like global.FooClass = js.constructorOf... 
  2) Static stuff, which is due for sjs inclusion, so not huge.
  3) Eval - It turns into strings that get evaluated... Is there a better way to integrate?
  
Potential better solutions:
  *) Generate a node module, then programatically require that? using the @JSImport stuff
  *) Do some post processing or use string substitution to use rql" .. ${fragment[Class]("name")} ..."
    fragment = some marker for which to execute the js.constructorOf[C], maybe like contextual?
    ???
